Question

6) A volume of 473 mL of oxygen was collected at 27°C. What volume would the oxygen occupy at

173°C?​

Answer 1

Answer : The volume of oxygen occupy at 173° would be, 703.2 mL

Explanation :

Charles' Law : It states that volume of the gas is directly proportional to the temperature of the gas at constant pressure.

Mathematically,

`(V_1)/(T_1)=(V_2)/(T_2)`

where,

`V_1\text{ and }T_1` are the initial volume and temperature of the gas.

`V_2\text{ and }T_2` are the final volume and temperature of the gas.

We are given:

`V_1=473mL\\T_1=27^oC=(27+273)K=300K\\V_2=?\\T_2=173^oC=(173+273)K=446K`

Now put all the given values in above equation, we get:

`(473mL)/(300K)=(V_2)/(446K)\\\\V_2=703.2mL`

Therefore, the volume of oxygen occupy at 173° would be, 703.2 mL
