Question 9
a chemistry student needs 85.0ml of carbon tetrachloride for an experiment. by consulting the crc handbook of chemistry and physics, the student discovers that the density of carbon tetrachloride is 1.59 gcm^-3 . calculate the mass of carbon tetrachloride the student should weigh out.
be sure your answer has the correct number of significant digits.

Mass of carbon tetrachloride 135.15 g.

Explanation:

Given data:

Volume of carbon tetrachloride = 85.0 mL or 85.0 cm³

Density of carbon tetrachloride = 1.59 g/cm³

Mass of carbon tetrachloride = ?

Solution:

Formula:

D=m/v

D= density

m=mass

V=volume

Now we will put the values in formula:

1.59 g/cm³ = m / 85.0 cm³

m = 1.59 g/cm³ ×85.0 cm³

m = 135.15 g

the dissolution of polymer can be thermodynamically described in 2 steps.
