Question

Calculate the volume in dm3 occupied by 60.0 g of ethane of STP.​

Answer 1

Answer:

22.4DM3

Explanation:

that 1 mol of any gas occupied the volume of 22.4 DM3

Answer 2

Answer:

48.8 dm³

Explanation:

Given -

Molecular formula of ethane = C2H6

Mass of ethane = 60 g

molar mass of ethane = 24g + 6 g → 30 g

Mole of ethane = given mass / Molar mass = 60 / 30 = 2 Mol

Number of mole = V/ 22.4 L

V = 2 × 22.4 ( L) = 44.8 L

Since 1 L = 1 dm³

Therefore volume of ethane = 48.8 dm³
