In this worksheet, we will practice calculating the purity of reactants and products and the effect of impurities on the percentage yield.
Q1:
A car travels 37.5 miles for every gallon of gasoline consumed, where 1 gallon is equivalent to 3.785 L. If gasoline is 84.2% carbon by mass and has a density of 0.8205 g/mL, calculate the mass of carbon dioxide produced during a journey of 500 miles.
- A 187 kg
- B 152 kg
- C 222 kg
- D 128 kg
- E 167 kg
Q2:
