Question

What is the mass in grams of 300 mL of salt water with a density of 1.30 g/cm^3

Answer 1

Answer: The mass of salt water is 390 grams

Step-by-step explanation:

To calculate the mass of salt water, we use the equation:

`\text{Density of substance}=\frac{\text{Mass of substance}}{\text{Volume of substance}}`

Density of salt water =
`1.30g/cm^3`

Volume of salt water = 300 mL =
`300cm^3` (Conversion factor:
`1mL=1cm^3` )

Putting values in above equation, we get:

`1.30g/cm^3=\frac{\text{Mass of salt water}}{300cm^3}\\\\\text{Mass of salt water}=(1.30g/cm^3* 300cm^3)=390g`

Hence, the mass of salt water is 390 grams
