Answer: [tex]H_2[/tex] < [tex]CO[/tex] < [tex]O_2[/tex] < [tex]CO_2[/tex] < [tex]CL_2[/tex]
Explanation:
According to avogadro's law, 1 mole of every substanceweighs equal to its molecular mass and contains avogadro's number [tex]6.023\times 10^{23}[/tex] of particles.
To calculate the moles, we use the equation:
[tex]\text{Number of moles}=\frac{\text{Given mass}}{\text {Molar mass}}[/tex]
1. Mass of [tex]H_2=moles\times {\text {Molar mass}}=0.50moles\times 2g/mol=1g[/tex]
2. Mass of [tex]O_2=moles\times {\text {Molar mass}}=0.50moles\times 32g/mol=16g[/tex]
3. Mass of [tex]Cl_2=moles\times {\text {Molar mass}}=0.50moles\times 71g/mol=35.5g[/tex]
4. Mass of [tex]CO_2=moles\times {\text {Molar mass}}=0.50moles\times 44g/mol=22g[/tex]
5. Mass of [tex]CO=moles\times {\text {Molar mass}}=0.50moles\times 28g/mol=14g[/tex]
Thus the flasks of gases in order of increasing grams of gas is:
[tex]H_2[/tex] < [tex]CO[/tex] < [tex]O_2[/tex] < [tex]CO_2[/tex] < [tex]CL_2[/tex]
