meriva

The concentration of NaOH is 25.00% by mass, it means that 25.00% of the mass of the solution is of NaOH. Hence:

$m_{NaOH}=25.00\%\times m_{solution}\Longrightarrow m_{NaOH}=\dfrac{25}{100}\times 0.250~g\iff\\\\\boxed{m_{NaOH}=0.0625~g}$

Answer:

The partial pressure is $P_p= 737.5 mm \ of \ Hg$

Explanation:

The Partial pressure of $H_2$ is mathematically represented as

$P_p = P_T -P_w$

Where $P_T$ is the total pressure of water with a value of 15.5 mm of Hg

$P_w$ is the partial pressure of water with a value 753 mm of Hg

Now substituting values

$P_p = 753-15.5$

$P_p= 737.5 mm \ of \ Hg$
