Answer: H_2 < CO < O_2 < CO_2 < CL_2

Explanation:

According to avogadro's law, 1 mole of every substanceweighs equal to its molecular mass and contains avogadro's number 6.023\times 10^{23} of particles.

To calculate the moles, we use the equation:

\text{Number of moles}=\frac{\text{Given mass}}{\text {Molar mass}}

1. Mass of H_2=moles\times {\text {Molar mass}}=0.50moles\times 2g/mol=1g

2. Mass of O_2=moles\times {\text {Molar mass}}=0.50moles\times 32g/mol=16g

3. Mass of Cl_2=moles\times {\text {Molar mass}}=0.50moles\times 71g/mol=35.5g

4. Mass of CO_2=moles\times {\text {Molar mass}}=0.50moles\times 44g/mol=22g

5. Mass of CO=moles\times {\text {Molar mass}}=0.50moles\times 28g/mol=14g

Thus the flasks of gases in order of increasing grams of gas is:

H_2 < CO < O_2 < CO_2 < CL_2
