Question

11. A sample contains 25% water and weighs 201 grams. Determine the grams of water in the

sample.

Answer 1

`m_(water)=50.25g`

Step-by-step explanation:

Hello,

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

`\% m/m=(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)=(\%m/m*m_(sample))/(100\%)\\ \\m_(water)=(25\%*201g)/(100\%)\\ \\m_(water)=50.25g`

Best regards.
