Answer:

C. 56 g

Explanation:

56 g S (1 mol S/ 32 g) = 1.75 mol S

1.75 mol O2 (32 g/ 1 mol O) = 56 g O2

The mass of oxygen gas contains the same number of moles as 56g of sulphur is 56g

Calculation,

Number of moles of sulphur = given mass/ molar mass of sulphur

Number of moles of sulphur = 56/ 32 moles

Number of moles of sulphur = 1.75 moles

According to question,

Number of moles of sulphur = Number of moles of oxygen(O2)

So, Let mass of oxygen be X.

Number of moles of oxygen = X/16×2 = 1.75 moles

Mass of oxygen (X) = 1.75×16×2 grams

Mass of oxygen (X) = 56 grams

The 6.022×1023 of chemical species like an electrons, molecules atoms, ions etc is called moles
