Question

A chemistry student needs 55.0g of dimethyl sulfoxide for an experiment. By consulting the CRC Handbook of Chemistry and Physics, the student discovers that the density of dimethyl sulfoxide is ·1.10gcm−3. Calculate the volume of dimethyl sulfoxide the student should pour out. Be sure your answer has the correct number of significant digits.

Answer 1

0.05 L

Step-by-step explanation:

The density is the mass that is occuping a volume, or the mass in each unity of the volume, so to calculate the volume, we just divide the mass by the density:

V = 55.0/1.10

V = 50.0 cm³

Knowing that 1 cm³ = 0.001 L, so V = 0.05 L.
