| **How many times is the number of molecules in 270 g of carbon greater than Avogadro’s number? The molar mass of carbon is 12 g / mol.**

Problem data: m (mass of taken carbon) = 270 g.

Reference values: according to the condition M (molar mass of carbon) = 12 g / mol.

The ratio of the number of molecules of the taken substance to the Avogadro number is equal to the amount of the substance and is determined by the formula: ν = m / M or ν = N / Na.

Let’s perform the calculation: ν = 270/12 = 22.5 mol (times).

Answer: The number of molecules in 270 grams of carbon taken will be 22.5 times greater than Avogadro’s number.
