Question

What is the percentage of insoluble sample in the unknown if the original sample had a mass of 2.732 g and that of the insoluble solid was determined to be 1.325 g? Don't include the % sign in your answer.

Answer 1

Answer: The percentage of insoluble solid in the unknown is 48.5

Step-by-step explanation:

To calculate the percentage of insoluble solid in the unknown sample, we use the equation:

`\%\text{ of insoluble solid}=\frac{\text{Mass of insoluble sample}}{\text{Mass of unknown sample}}* 100`

Mass of unknown sample = 2.732 g

Mass of insoluble solid = 1.325 g

Putting values in above equation, we get:

`\%\text{ of insoluble solid}=(1.325g)/(2.732g)* 100=48.5\%`

Hence, the percentage of insoluble solid in the unknown is 48.5
