What is the mass of a sample f a substance with a volume of 120ml and a density of 0.75g?
density has to be in units of mass/volume, or grams/ml in your case. If density is 0.75 g/ml, then mass = .75 x 120 = 90 grams. Check the question again to be sure
How do you figure weight of an object suspended at a 90 degree angle?
You weigh it, failing that ability you need to know the composition, density and dimensions.
How many degrees are in a quarter of a turn?
A quarter turn is 90 degrees. This is based on a full circle of 360 degrees.
If a student has a mass of 90 kg what is the students weight?
A mass of 90 kg weighs 882 newtons (198.4 pounds) on the earth. (rounded)
If a student has a mass of 90 kg what is the student's weight?
A student with a mass of 90 kg on the earth (gravity =9.8m/s/s) will have a weight of 882 Newtons. Weight = Mass * Gravity
If 90 percent of an object is floating below water what is its density?
Let's say the object has mass M and volume V. An object floats by displacing an amount of water equal to the object's mass. So water equal to 90% of the volume of the object has mass equal to the whole object, or M = 0.9V * 1g/ml or M = 0.9V Since density is mass divided by volume, or d = M/V, density of object = M/V = 0.9 g/ml.
What is the density of an object that has a volume of 90 cubic centimeters and a mass of 360 grams?
Density= Mass (in grams)/ Volume (in milliliters) So convert to the correct units.. 1 cc= 1 mL, so 90 cc= 90 mL Density= 360 g/ 90 mL = 4 g/mL
A substance has a mass of 90 g and occupies a volume of 15 ml What is the density of this substance?
D = m/V D = 56g/15ml D = 3.7g/ml
What is the density of an object with a mass of 90 grams and a volume of 30 cm?
Volume cannot be measured in cm since that is a unit for measuring length.
Whats 90 mg in Ml?
It depends on the density of the object
What is the mass of a sample f a substance with a volume of 120ml and a density of 0.75g?
density has to be in units of mass/volume, or grams/ml in your case. If density is 0.75 g/ml, then mass = .75 x 120 = 90 grams. Check the question again to be sure
What is the density of a object with a mass of 90 grams and a volume of 30 centimeters?
Volume cannot be measured in centimetres. Without the volume in appropriate units, the question makes no sense and so cannot be answered.
How do you figure weight of an object suspended at a 90 degree angle?
You weigh it, failing that ability you need to know the composition, density and dimensions.
What is 90 liters equal to in pounds?
A liter is a unit of volume, not a unit of mass (or weight) like the pound. To convert between mass and weight, you need to know the density of a substance. The formula that relates volume and mass is: mass = volume x density You'll probably find density in units such as kilogram / liter (or the equivalent gram/cubic centimeter); if you use this in the formula, you'll get the mass in kilograms. You can then convert that to pounds.
How many grams of calcium carbonate are required to prepare 50.0 g of calcium oxide?
This is a mass stoichiometry problem. Start with the balanced equation: CaCO3 --> CaO + CO2. Do a conversion from 50g CaO to moles: 56g/1mol=50g/x, x=.9 moles. The equation is balanced as written, with all coefficients understood to be 1. So: .9 moles CaO means .9 moles CaCO3. Do another conversion from moles to grams: 100g/1mol=x/.9 moles. Solve for x to get 90 grams. (56g=molar mass of calcium oxide; 100g=molar mass of calcium carbonate.)
What metal has a mass of 61.0g and a volume of 5.40cm?
Iorn
If you have a mass of 90 kg and take g equals 10 meters per second squared what is the weight of this object?
Weight = m g = (90 x 10) = 900 newtons
