Question

Find the volume of 20 g of H2 at STP.

Answer 1

given mass/molar mass = given volume/ total volume

so,

20/2 = x/22.4 (let x be the given volume)

20/2 × 22.4 = x

x = 224 litres

pls mark as brainiest answer

Answer 2

Answer:

by dude ur answer is

Explanation:

We already know that

1 mole of any gas occupies 22.4 litres at STP.

Here,given weight of hydrogen is 20 g

Molecular weight of hydrogen is 2 g

No.of moles = given weight/molecular weight

→ = 20/2 = 10 moles

1 mole -------------22.4 litres

10 moles ------------?

→ 10 moles × 22.4 litres / 1 mole

→ 224 litres

volume of 20 g of hydrogen at STP is 224 litres
