Question

calculate the volume of the dm cube occupied by 60gm of ethane of STP​

Answer 1

Answer:

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
