Answer 1

Answer:

$m_{water}=50.25g$

Explanation:

Hello,

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

$\% m/m=\frac{m_{water}}{m_{sample}}*100\%$

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:

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

Best regards.
