What is the mass of 0.9210 moles of sulfur dioxide gas (SO2)?

58.944 g

Explanation:

From the question given above, the following data were:

Mole of SO2 = 0.9210 mole

Mass of SO2 =?

Next, we shall determine the molar mass of SO2. This can be obtained by adding the molar mass of sulphur and oxygen together as illustrated below:

Molar mass of SO2 = 32 + (2 × 16)

= 32 + 32 = 64 g/mol

Finally, we shall determine the mass of 0.9210 mole of SO2 as follow:

Mole of SO2 = 0.9210 mole

Molar mass of SO2 = 64 g/mol

Mass of SO2 =?

Mole = mass /Molar mass

0.9210 = mass of SO2 / 64

Cross multiply

Mass of SO2 = 0.9210 × 64

Mass of SO2 = 58.944 g

Thus, the mass of SO2 is 58.944 g.
