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 density of a 600 gram metal with a volume of 30 ml?
Density = Mass/Volume = 600/30 = 20 grams per ml.
What is 200 grams per liter to percent?
To convert 200 grams per liter to percent, you divide the grams by the total volume in milliliters (1 liter = 1000 milliliters). Thus, 200 grams per liter is equivalent to 200 grams in 1000 milliliters, or 20% (since 200 grams in 1000 mL is the same as 20 grams in 100 mL). Therefore, 200 grams per liter is 20%.
How many milliliters in 20grams?
Milliliters is volume and grams is mass, so you need to know mass density to solve this. For water, it has mass density of 1 gram per cubic centimeter which is the same as 1 gram per millitre of volume. So for water only, 20 ml = 20 grams.
If a 2 inch cube is 20 grams how heavy is an 8 inch cube of the same material How is this Calculated?
The volume of the little cube is 23 = 8 cubic inches so the density of the material is 8/20 = 0.4 grams per cubic inch.The volume of the large cube is 83 = 512 cubic inches, so the mass (not the weight) is 512*0.4 = 128 grams.
