A sample thought to be pure lead occupies a volume of 15.0 mi.and has a mass of 160.0g.determine the density and is the sample pure lead?
The density of the sample is calculated by dividing the mass (160.0g) by the volume (15.0 mi^3), which results in 10.67 g/cm^3. The density of pure lead is known to be 11.34 g/cm^3, suggesting that the sample is not pure lead but likely a different material with a lower density.
How can you determine pure silver if you know its volume and mass?
The density of pure silver is 10.5 grams per cubic centimeter. If you have the exact volume of the coin in CCs, you can calculate the weight that it would be were it pure silver. If it differs substantially from the calculated value, it is an alloy.
Calculate theh mass of a sample of pure silver density equals 10 49 g cm that has a volume of 12.99cm?
To calculate the mass of the silver sample, we use the formula: Mass = Density x Volume. Given density = 10.49 g/cm^3 and volume = 12.99 cm^3, the mass would be 10.49 g/cm^3 * 12.99 cm^3 = 135.88 grams.
Why density is the criteria for purity with respect to chemistry?
Mass and volume are extensive properties, which are dependent upon the size of the sample. A larger sample will have a greater mass and volume than a smaller sample. Density is an intensive property, which does not depend on the size of the sample. Density is a ratio of mass to volume, which does not vary with the size of the sample. The density of a larger sample will be the same as the density of a smaller sample.
A sample of 0.53 grams of an ore contains 5.4 percent silver How many milligrams of pure silver are in the sample?
To calculate the amount of pure silver in the sample, multiply the mass of the ore by the percentage of silver: 0.53 grams * 5.4% = 0.02862 grams of silver. To convert grams to milligrams, multiply by 1000: 0.02862 grams * 1000 = 28.62 milligrams of pure silver in the sample.
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 property like volume depends of the size of the sample?
The property that depends on the size of the sample is extensive. Extensive properties, such as mass and energy, scale with the size of the sample. This means that as the sample size increases, the value of the property also increases proportionally.
How do you calculate mass of a pure copper?
The mass of pure copper can be calculated by measuring its volume and then using the density of copper (8.96 g/cm^3) to determine the mass. The formula for calculating mass is: mass = volume x density.

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
Calculate theh mass of a sample of pure silver density equals 10 49 g cm that has a volume of 12.99cm?
To calculate the mass of the silver sample, we use the formula: Mass = Density x Volume. Given density = 10.49 g/cm^3 and volume = 12.99 cm^3, the mass would be 10.49 g/cm^3 * 12.99 cm^3 = 135.88 grams.

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.
Compute the density of an 820g sample of pure silicon occupying a 350cm3 container?
Density is calculated as mass divided by volume. In this case, the mass of the silicon sample is 820g and the volume of the container is 350 cm^3. Therefore, the density of the silicon sample in the container is 820g / 350 cm^3 = 2.34 g/cm^3.
Is the density of a fluid the limit of the mass per unit volume as the voulume aproaches a value for which the ratio exists?
The definition doesn't require that level of complexity. Any physical sample of any solid, fluid, or gasmust have both mass and volume, and so the ratio must exist. Can you think of an exception ?As long as the sample is pure, the ratio should be independent of the size of the sample.
How do you calculate the mass of water from its density?
To calculate the mass of water, you can multiply the density of water (1 g/cm3 or 1000 kg/m3) by the volume of water. The formula is: mass = density x volume. For example, if you have 1 liter of water, the mass would be 1000 grams.
