Question

If 13.5 g NaCI were dissolved in 250.0 g of water, what is the mass percent of NaCI in the solution? What is the mass percent of water in the solution?

Answer 1

Answer: The mass percent of
`NaCl` is 6.3 % and mass percent of water is 93.7%.

Step-by-step explanation:

To calculate the mass percent of element in a given compound, we use the formula:

`\text{Mass percent }=\frac{\text{Mass of given compound}}{\text{Total mass}}* 100`

Given :

Mass of
`NaCl` = 13.5 g

Mass of water = 250.0 g

Putting values in above equation, we get:

`\text{Mass percent of}NaCl=(13.5)/(13.5+250.0)* 100=6.3\%`

Hence, the mass percent of
`NaCl` is 6.3 %.

Putting values in above equation, we get:

Hence, the mass percent of water is 93.7 %.
