How many grams are in 3.58 x 10^23 molecules of dicarbon hexahydride?

Mass = 18 g

Explanation:

Given dа ta:

Number of molecules of Dicarbon hexahydride = 3.58 * 10²³ molecules

Mass of Dicarbon hexahydride = ?

Solution:

The given problem will solve by using Avogadro number.

It is the number of atoms, ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.

The number 6.022 * 10²³ is called Avogadro number.

For example,

3.58 * 10²³ molecules * 1 mol / 6.022 * 10²³ molecules

0.6 mol

Mass of Dicarbon hexahydride:

Mass = number of moles * molar mass

Mass = 0.6 mol * 30 g/mol

Mass = 18 g
