Q:
# At 20 degrees Celsius a mixture of 46.63mL of carbon disulfide and 46.63mL of ethyl acetate has a volume of 94.52mL. if the densities (at this temperature) of carbon disulfide and ethyl acetate are 1.2559g/mL and 0.8890g/mL, respectively, what is the density of the mixture?

Accepted Solution

A:

Mass of carbon disulfide = 46.63 mL Γ 1.2559 g/mL = 58.56 g
Mass of ethyl acetate = 46.63 mL Γ 0.8890 g/mL = 41.45 g
Total mass = 58.56 g + 41.45 g = 100.01 g
Total volume = 94.52 mL = 94.52 g (since 1 mL β 1 g for water-like substances)
Density of mixture = Total mass / Total volume = 100.01 g / 94.52 g β 1.058 g/mL
