If the density of a substance is 5g/cm3 and the volume is 10cm3,
determine the mass.

Explanation:

Density is the amount of mass per unit volume, so the formula is:

The density of the substance is 5 grams per cubic centimeter and the volume is 10 cubic centimeters.

d= 5 g/cm³ v= 10 cm³

Substitute the values into the formula.

We are solving for the mass, so we have to isolate the variable m. It is being divided by 10 cubic centimeters. The inverse of division is multiplication, so we multiply both sides of the equation by 10 cm³.

The units of cubic centimeters (cm³) cancel.

The mass of the substance is 50 grams.

Neptune is the eighth planet from the sun. it was the first planet to get its existence predicted by  mathematical calculations  before it was actually seen through a telescope on sept. 23, 1846. irregularities in the orbit of  uranus  led french astronomer alexis bouvard to suggest that the gravitational pull from another celestial body might be responsible. german astronomer johann galle then relied on subsequent calculations to   spot neptune via telescope. previously, astronomer galileo galilei sketched the planet, but he mistook it for a star due to its slow motion. in accordance with all the other planets seen in the sky, this new world was given a name from greek and roman mythology — neptune, the roman god of the sea.
