Question

A bottle contains 3.100 ml of a liquid. the total mass of the bottle and the liquid together is 6.300 g. the mass of the empty bottle is 4.240 g. what is the density of the liquid? a 0.665 g/ml b 2.032 g/ml c 1.505 g/ml d 1.368 g/ml

Answer 1

Answer : The density of the liquid is (a) 0.665 g/mL

Explanation : Given,

Volume of a liquid = 3.100 mL

Mass of empty bottle = 4.240 g

Total mass of bottle and the liquid = 6.300 g

First we have to calculate the mass of a liquid.

Mass of liquid + Mass of empty bottle = Total mass of bottle and liquid

Mass of liquid + 4.240 g = 6.300 g

Mass of liquid = 6.300 - 4.240 = 2.06 g

Now we have to calculate the density of a liquid.

$Density=\frac{Mass}{Volume}$

$Density=\frac{2.06g}{3.100mL}=0.665g/mL$

Therefore, the density of the liquid is 0.665 g/mL

Answer 2

The answer is a. 0.665 g/m
