An iron ore sample is found to be 35.00 percent Fe by mass How many grams of ore is needed to obtain 454.0 grams of Fe?
To calculate this, you first need to determine the mass of pure iron in 454.0 grams. This is done by multiplying 454.0 grams by 0.35 (the decimal equivalent of 35.00%). This gives 158.9 grams of pure iron. To find out how many grams of ore is needed, you need to set up the equation 0.35 * Mass of ore = 158.9 grams, which gives you 454 grams of ore needed.
How much does iron weigh per cubic centimeter?
The number listed most frequently on the www for the density of pure iron at room temperature is 7.874 grams of mass per cubic centimeter. On Earth, 7.874 grams of mass weighs 0.0772 newtons (rounded), or 0.278 ounce avdp.
How will the mass of a pure substance be affected when the volume is increased?
The mass of a pure substance will remain constant even if the volume is increased. The mass of a substance is an intrinsic property that does not change with changes in volume.
If there are 3 grams of iron in a sealed container with most air the sealed container with iron moist air weighs a total 5 grams will there be 3 grams of rust if all the iron rusts?
Yes, if all the iron rusts, it will convert to iron oxide, which has a higher molecular weight. The total weight will increase to 5 grams. So, there will be 3 grams of rust formed in this process.
What is the density of an object with a mass of 5g that raises the volume of water from 30mL to 45mL?
5 grams. This however is by definition. The mass of water is quite variable depending on temperature and contaminants. The definition includes 1.) pure water, 2.) standard pressure 14.7 psia, 3.) standard temperature 4 degrees C.
The density for a sample of a pure material with a volume of 5 cm3 and a mass of 20 grams is?
The idea is to divide the mass by the volume.
What is the mass of a pure platinum disk with a volume of 113 with a density of platinum is 21.4?
The mass of the platinum disk can be calculated using the formula: mass = volume * density. Plugging in the values gives mass = 113 * 21.4 = 2428.2 grams. Therefore, the mass of the pure platinum disk is 2428.2 grams.
The density of pure diamond is 3.5 gcm3 The mass of a diamond is 0.25 grams Calculate its volume?
Density = Mass/Volume so Volume = Mass/Density Vol = 0.25/3.5 = 0.071429 cubic cm
300 grams equals how many mils?
Grams are a measurement of weight, millilitres are a meaurement of volume. The standard for the metric volume (put in lamens terms) of the litre is the amount of space taken up by one kilogram in weight of pure water therefore the volume taken up by 300 millilitres of pure water will weigh 300 grams. That is of course if you are measuring 300 grams of pure water, if you have 300 grams of an item that has a different mass and density to pure water you will then have that item taking up a different amount of volume. This difference in volume can be quite dramatic depending on the density and mass of the item.
How much does iron weigh?
A single iron atom weighs 55.845 atomic mass units.The weight of a quantity of pure iron will vary depending on the volume and gravitational acceleration. The mass of iron will also vary depending on the given volume. Given the density at room temperature, 7.874 g·cm−3 and the volume of iron, you can find the mass by multiply the density and the volume. To find the weight of an object, you would need to multiply its mass by the local gravitational acceleration.
What is the density of a 64-g iron cube that displaces 8 mL of water?
Depends what metal. If I might add to the above, you cannot calculate the density of a substance without knowing its mass (weight) and its volume, since density is mass per unit volume. On the other hand, if you know the type of metal, and that it is pure, you can simply look up the density in a table since the density of all substances is constant for that substance, regardless of the weight or volume of the sample.
What is 73 grams in ml?
This is not a valid conversion; milligrams (mg) and grams (g) are measures of weight or mass while milliliters (mL or ml) measure volume.
What is the ml of 0.23 kg of pure water?
The mass of 0.23 kg of pure water is equal to 230 grams. Given that the density of pure water is 1 g/ml, the volume of 230 grams of water would be 230 ml.
What is the mass of 6.5 centimeters cube iron?
To determine the mass of Iron, its density is required. The formula used is Volume x Density = Mass. Assuming the Iron is pure and in solid state with a density of approximately 7.87g/cm3 at room temperature, its mass is around 51.2g.
What is the mass of 4.00 moles of iron?
To determine the mass of Iron, its density is required. The formula used is Volume x Density = Mass. Assuming the Iron is pure and in solid state with a density of approximately 7.87g/cm3 at room temperature, its mass is around 51.2g.
If you have the mass of an object how do you find the volume?
If you know the mass of an object, you can find the volume if you know the density. Since Density = mass/volume (D=M/V) , the volume is the mass divided by the density (V = M/D).The mass tells you the physical amount, as in number of atoms, molecules, or moles present, which on Earth means the effective weight. In order to find the volume, which is the space that the object or substance takes up, you need to know the density of the material, i.e.. how concentrated the mass is.Given a fixed mass, both volume and density can change with conditions, especially for gases.Density = mass/volume so that Volume = mass/densityExample:1000 grams of pure elemental IronSolid iron at standard temperature has a density of 7.87 g/cm3So 1000 grams/7.87 g/cm3 gives a volume of about 127 cm3(a kilogram of iron can make a cube about 5 cm on a side)
An iron ore sample is found to be 35.00 percent Fe by mass How many grams of ore is needed to obtain 454.0 grams of Fe?
To calculate this, you first need to determine the mass of pure iron in 454.0 grams. This is done by multiplying 454.0 grams by 0.35 (the decimal equivalent of 35.00%). This gives 158.9 grams of pure iron. To find out how many grams of ore is needed, you need to set up the equation 0.35 * Mass of ore = 158.9 grams, which gives you 454 grams of ore needed.
