Question

You have 125 g of a certain seasoning and are told that it contains 94.0 g of salt. What is the percentage of salt by mass in this seasoning?

Answer 1

To find the percentage of salt by mass in the seasoning, the mass of salt (94.0 g) is divided by the total mass of the seasoning (125 g) and then multiplied by 100%, resulting in 75.2%.

Step-by-step explanation:

To calculate the percentage of salt by mass in the seasoning, we need to use the mass of the salt and the total mass of the seasoning. The formula for calculating percent by mass is:

Percent by mass = (mass of solute / total mass of solution) × 100%

Here, the mass of the solute (salt) is 94.0 g and the total mass of the seasoning is 125 g. Plugging these values into the formula, we get:

Percent by mass = (94.0 g / 125 g) × 100%

Solving this gives us:

Percent by mass = 0.752 × 100%

Percent by mass = 75.2%

Therefore, the percentage of salt by mass in the seasoning is 75.2%.

Answer 2

To work out the percentage, divide the actual amount of salt by the total mass of the seasoning and multiply by 100. (94/125) x 100 = 75.2.
