density = mass/volume = 350/150 = 2.33 grams/cubic centimeter

Density = Mass/Volume = 50g/12.5mL = 4 g per mL

density = mass divided by volume = 100/25 = 4 grammes per cubic centimetre.

15g/cm^3

There can be no sensible answer to the question because the question provides no information on the units used. Consequently, there is no guarantee that the units for measuring volume are the same as the those used as the denominator for density. For example, if the volume is in cubic cm and the density is in grams per cubic cm, the calculated mass would be in grams. But with the same density, if the volume were litres, the mass would be kilograms. It gets even more complicated if the volume is in gallons!

The density of the rock is 20 grams/cm3. You can calculate density by dividing the mass by the volume.

The density of the rock is calculated by dividing its mass (56 grams) by its volume. If the volume is unknown, then the density cannot be determined. Density is the mass per unit volume of a substance, so both mass and volume need to be known to calculate it.

The density of the rock is calculated by dividing the mass (35 grams) by the volume (7.0 cubic centimeters). Density = mass/volume, so the density of the rock would be 5 grams per cubic centimeter.

To find the density, divide the mass of the rock (15 grams) by its volume (30 milliliters). Density = mass/volume, so in this case 15 grams / 30 milliliters = 0.5 grams per milliliter. Therefore, the density of the rock is 0.5 g/mL.

Density simply means mass per unit of volume. So, 120 grams divided by 25 cc = 4.8 grams / cc (density).

density = mass/volume = 350/150 = 2.33 grams/cubic centimeter

The density of the rock can be calculated by dividing its mass (24.5 grams) by its volume (8.7 cm3). Density = Mass/Volume. Therefore, the density of the rock is approximately 2.82 grams per cubic centimeter.

Density = Mass/Volume = 25g/5ml = 5 grams per mL.

Density = Mass/Volume = 50g/12.5mL = 4 g per mL

3 grams /cm3

To determine the volume of a substance given its mass, you need to know its density. Without the density information, it is not possible to accurately calculate the volume. Density is the ratio of mass to volume.

density = mass divided by volume = 100/25 = 4 grammes per cubic centimetre.
