Question

6. What weight of hydrogen at STP could be contained in a
vessel that holds 3.36 L 0, gas at STP?
(a) 0.21 g
(b) 4.8 g
(c) 0.30 g
(d) 3.36 g​

Answer 1

Answer:

wkt 22.4L means 1 mol at stp. that means 3.36L means 0.15 mol.therefore the mass of H2 in the given sample is 0.15×2=0.3g

Answer 2

Answer:

(c) 0.30g

Explanation:

1mole of Hydrogen (H2) gas occupies 22.4liter

how many moles of H2 occupies 3.36liter

= (3.36*1)/22.4

= 0.15 mol

1 mole of H2 is 2g/mol

0.15 mole is how much grams?

= (0.15*2)/1

= 0.3g

so option c is the right answer, i.e

0.30g
