Question

You have 125 g of a certain seasoning and are told that it contains 92.0 g of salt. What is the percentage of salt by mass in this seasoning?

Answer 1

92.0g/ 125g = .736
.736•100 = 73.6%

Answer 2

Answer: The percentage of salt by mass in the seasoning is 73.6 %

Explanation:

To calculate the percentage composition of a substance in a mixture, we use the equation:

$\%\text{ composition of substance}=\frac{\text{Mass of substance}}{\text{Mass of mixture}}\times 100$

We are given:

Mass of salt = 92 g

Mass of mixture (seasoning) = 125 g

Putting values in above equation:

$\%\text{ composition of salt}=\frac{92}{125}\times 100=73.6\%$

Hence, the percentage of salt by mass in the seasoning is 73.6 %.
