Answer:

d = 1.8 g/mL

Explanation:

Given data:

Mass of bottle = 6.8 g

Volume of liquid = 23.1 mL

Mass of bottle + liquid = 48.8 g

Density of liquid = ?

Solution:

First of all we will calculate the mass of liquid.

Mass of liquid = combined mass - mass of bottle

Mass of liquid = 48.8 g - 6.8 g

Mass of liquid = 42 g

Density of liquid:

d = m/v

d = 42 g/ 23.1 mL

d = 1.8 g/mL
