A chemistry student needs 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 . Calculate the volume of carbon tetrachloride the student should pour out. Be sure your answer has the correct number of significant digits.

34.6 cm³

Explanation:

A chemistry student needs 55.0 g 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 g/cm³. Calculate the volume of carbon tetrachloride the student should pour out. Be sure your answer has the correct number of significant digits.

Step 1: Given data

Step 2: Calculate the required volume of carbon tetrachloride

Density is an intrinsic property of matter. It can be calculated as the quotient between the mass of the sample and its volume.

ρ = m/V

V = m/ρ

V = 55.0 g/(1.59 g/cm³)

V = 34.6 cm³

The chemistry student should pour 34.6 cm³ of carbon tetrachloride.

the first point, i am pretty sure.

what is the general relationship between a galaxy's distance from earth and its speed?

the answer is:

the farther away a galaxy is from us, the faster it is moving away from us.
