Answer 2

Answer:

The volume of 0.44 grams CO is equal of 0.02 grams of hydrogen gas at NTP. Therefore the correct option is (1).

Explanation:

At NTP, we know the volume of 1 mole of gas = 22.4 L

Molecular mass of CO = 28g

So, the number of moles of CO  = 0.44/28 = 0.01

Volume of CO in 0.01 mole = 22.4 × 0.01 = 0.224 L

Now, the number of moles of H2 = 0.02/2 g = 0.01 mole

Therefore, volume of H2 in 0.01 mole at NTP = 22.4 × 0.01 = 0.224 L

Hence, the volume of 0.44 grams CO is equal of 0.02 grams of hydrogen gas at NTP.
