Question

Calculate mass 112ml of H2 at STP

Answer 1

Explanation:

Given -

• 112 mL of H2 at STP

To Find -

• mass

As we know that :-

• volume = n × 22400 (in mL)

It means,

» 112 = n × 22400

» n = 112/22400

• » n = 1/200

And

As we know that :-

• mass = n × GAM

» 1/200 × 2

» 1/100

• » 0.01 g

Hence,

The mass of 112 mL of H2 at STP is 0.01 g
