Question

An empty container weighs 80.21 g. it is filled with 20.14 mL of an unknown liquid, and the total weight of the container and liquid is 105.22 g. What is the density of the liquid?

Answer 1

1.242 g/mL

Step-by-step explanation:

Step 1: Given data

Mass of the empty container (m₁): 80.21 g

Mass of the filled container (m₂): 105.22 g

Volume of the unknown liquid (V): 20.14 mL

Step 2: Calculate the mass of the liquid

The mass of the liquid is equal to the difference between the mass of the filled container and the mass of the empty container.

`m = m_2 - m_1 = 105.22g - 80.21 g = 25.01 g`

Step 3: Calculate the density of the unknown liquid

The density of the liquid is equal to its mass divided by its volume.

`\rho = (m)/(V) = (25.01g)/(20.14mL) = 1.242 g/mL`
