If an object has a mass of 3 g and a volume of 10 cm3 what is its density?
3 g/10 cm3 = 0.3 g/cm3 and this is the density, since density is expressed as mass/volume.
What calculate the density of a substance with a mass of 35.0 g and a volume of 25.0 cm3?
density = mass ÷ volume= 35g ÷ 25 cm3= 1.4 g/cm3 (= 1.4 gcm-3)Density = Mass/Volume = 35.0/25.0 = 1.4 g per cm3
What is the mass and volume of 1kg of silver?
The mass of 1 kg is 1 kg (or 1000 g). Taking the density of silver at 10.49 grams per cubic centimeter. For volume, divide: (1000 g) ÷ (10.49 g/cm3) = 95.3289 cm3, or 0.09533 liters.
What is the radius of a solid aluminum sphere that has a mass of 87g in inches?
Mass = 87 grams and density of aluminium = 2.7g/cm3 So volume of spere = Mass/Density = 87/2.7 = 32.22... cm3 Then V = 4/3*pi*r3 = 32.22.. cm3 r3 = 32.22...*3/(4*pi) = 7.6925 so that r = 1.97 cm = 0.78 inches.
What is the mass of a pure silver with a density of 10.49 g and a volume of 12.99 cm3?
Density is not measured in grams so nothing can have a density of 10.49 g. Assuming that the intended density is 10.49 g/cm3 then mass = density*volume = 10.49*12.99 = 136.27 grams, approx.
