Answer
a) 1.12 kg
b) 0.78 kg
Work Step by Step
a. To calculate the mass of ethanol in 1.50 qt of ethanol, we can use the density of ethanol from Table R-5, which is 0.789 g/mL.
First, we need to convert 1.50 qt to mL:
1.50 qt = 1.50 x 946.4 = 1419.6 mL
Then we can use the formula: mass = density x volume
mass = 0.789 g/mL x 1419.6 mL = 1119.9744 g.
So the mass of ethanol in 1.50 qt is 1119.9744 g\approx 1.12 kg.
b. To calculate the mass of mercury in 3.5 in^3 of mercury, we can use the density of mercury from Table R-5, which is 13.596 g/mL.
First, we need to convert 3.5 in^3 to mL:
3.5 in^3 = 3.5 x 16.387 = 57.35 mL
Then we can use the formula: mass = density x volume
mass = 13.6 g/mL x 57.35 mL = 779.96 g
So the mass of mercury in 3.5 in^3 is 0.78 kg.
