Answer:

[tex]m_{water}=50.25g[/tex]

Explanation:

Hello,

In this case, considering that the by-mass percent of water is:

[tex]\% m/m=\frac{m_{water}}{m_{sample}}*100\%[/tex]

Given such percent and the mass of the sample, we can find the mass of water in grams in the sample by solving for it as shown below:

[tex]m_{water}=\frac{\%m/m*m_{sample}}{100\%}\\ \\m_{water}=\frac{25\%*201g}{100\%}\\ \\m_{water}=50.25g[/tex]

Best regards.
