Question

A flask that weighs 345.8 g is filled with 225 mL of carbon tetrachloride. The weight of the flask and carbon tetrachloride is found to be 703.55 g. From this information, calculate the density of carbon tetrachloride

Answer 1

Answer:

1.59g/mL

Explanation:

Mass of CCl₄ = mass of flask and CCl₄ − mass of empty flask

m = 703.55 g − 345.8 g

m = 357.75 g

Density = mass / volume

d = 357.75 g / 225 mL

d = 1.59 g/mL

Answer 2

Given - Weight and volume

Find - Density

Solution - Density is calculated by the formula - mass/volume

Volume of carbon tetrachloride = 225 ml

Mass of carbon tetrachloride = Combined mass - mass of flask

Mass of carbon tetrachloride = 703.55 - 345.8

Performing subtraction

Mass of carbon tetrachloride = 357.75 grams

Keep the values in formula of density.

Density = $\frac{357.75}{225}$

Performing division

Density = 1.59 g/ml

Hence, density of carbon tetrachloride is 1.59 g/ml.
