Question

calculate the mass of sulphur dioxide gas having 0.1 mole

Answer 1

Mass of so2 = 64

0.1 X 64= 6.4

Answer 2

Concept:

The mass divided by the molar mass yields the number of moles.

Given:

The number of moles of SO₂ = 0.1 mole

Find:

Calculate the mass of sulfur dioxide gas having 0.1 mole

Solution:

The mass of a compound can be calculated as follows below.

           Mass = Number of moles x Molar mass

Molar mass of sulfur dioxide (SO₂) = 1xS + 2xO

                    = 1x32 g/mol + 2x16 g/mol

                    = 32 g/mol + 32 g/mol

                    = 64 g/mol

By substituting the given values in the above expression, we get.

           Mass = 0.1 mol x 64 g/mol

           Mass = 6.4 g

Hence, the mass of sulfur dioxide gas having 0.1 moles is 6.4 grams.
