Answer: The pressure of the hydrogen in the gas-collecting tube is 721.3 mm Hg
Explanation:
According to Dalton's law, the total pressure is the sum of individual pressures.
[tex]p_{total}=p_{H_2O}+p_{H_2}[/tex]
Given : [tex]p_{total}[/tex] =total pressure of gases = 741.1 mm Hg
[tex]p_{H_2O}[/tex] = partial pressure of water = 19.8 mm Hg
[tex]p_{H_2}[/tex] = partial pressure of hydrogen = ?
putting in the values we get:
[tex]741.1 mm Hg=19.8mmHg+p_{H_2}[/tex]
[tex]p_{H_2}=721.3mm Hg[/tex]
Thus the pressure of the hydrogen in the gas-collecting tube is 721.3 mm Hg
According to the Dalton Law in a blend of non-reacting gases, the entire pressure will be equivalent to the total of partial pressures of the individual gases.
The pressure of H₂ gas collected in the tube will be 721.3 mm Hg.
This can be calculated by:
Dalton's formula:
[tex]\text{p}_{\text{total}} & = \text{p}\text{H}_{2} \text{O} + \text{p} \text{H}_{2}[/tex]
Given :
- [tex]\text{p}_{\text{total}}[/tex] = total pressure of gases = 741.1 mm Hg
- [tex]\text{p}\text{H}_{2} \text{O}[/tex] = partial pressure of water = 19.8 mm Hg
- [tex]\text{p} \text{H}_{2}[/tex]= partial pressure of hydrogen = ?
Now using the formula we will calculate:
[tex]\text{741.1 mm Hg} & = \text{19.8 mm Hg} + \text{p} \text{H}_{2}[/tex]
[tex]721.3 \;\text {mm Hg} = \text{p} \text{H}_{2}[/tex]
Therefore, the pressure of the hydrogen in the tube is 721.3 mm Hg.
