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.

Respuesta :

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

Explanation:

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

[tex]\%\text{ of insoluble solid}=\frac{\text{Mass of insoluble sample}}{\text{Mass of unknown sample}}\times 100[/tex]

Mass of unknown sample = 2.732 g

Mass of insoluble solid = 1.325 g

Putting values in above equation, we get:

[tex]\%\text{ of insoluble solid}=\frac{1.325g}{2.732g}\times 100=48.5\%[/tex]

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