Question

As an empty 1,000-mililiter container has a mass of 250.0 grams. When flled with a liquid, the container and the liquid have a combined mass of 1,300. grams. What is the density of the liquid?

Answer 1

• Density =mass/volume
• mass =1300-250=1050gm
• volume =1000ml=1000cc(cubic centimeter
• density =1050÷1000=1.05g/cc

Answer 2

The density of liquid is 1.05 g/mL

Explanation:

We are given:

Mass of container, $m_1$ = 250 g

Mass of container + liquid, m = 1300 g

Mass of liquid = $(m-m_1)=(1300-250)g=1050g$

To calculate density of a substance, we use the equation:

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

We are given:  

Mass of liquid = 1050 g

Volume of liquid = 1000 mL

Putting values in above equation, we get:

$\text{Density of liquid}=\frac{1050g}{1000mL}\\\\\text{Density of liquid}=1.05g/mL$
