O MATTER Using mass density to find mass or volume Terek A chemistry student needs 80.0 mL 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 1.10 g cm. Calculate the mass of dimethyl sulfoxide the student should weigh out. Be sure your answer has the correct number of significant digits. alo Ar
Solution
Solution
We know that
Mass = Volume × Density
Where, Volume = 80.0 mL = 80.0 cm -1 , Density = 1.10 g.cm -1
Putting these values into the above equation then we get
Mass = 80.0 cm -1 × 1.10 g.cm -1
Mass = 88.0 g = 8.80 × 10 -1 g
