16. A mixture is made by adding 20.42 g of substance A, 1.322 g of substance B, and 83.1 g of substance C. Calculate the total mass of the mixture with the proper number of significant figures. 17. The average speed of a nitrogen molecule in air at 25 °C is 515 m/s. Convert this speed to miles per hour.

1. In the olden days, US minted pennies were pure copper, but copper got so expensive that a pure copper penny was worth more than I cent. Modern pennies are composed of zinc and coated with copper. A student determines the mass of a penny to be 2.482 g. After making several scratches in a penny, the student puts the penny into hydrochloric acid, where the zinc (but not the copper) reacts with hydrochloric acid via a single replacement reaction. The hydrogen is collected at 25°C over water. The collected gas occupies 0.899 L at a total pressure of 791 mm Hg. A. Calculate the moles of hydrogen produced in the reaction. (Hint: Use the Table 1. to determine the vapor pressure of water and assume that all of the zinc in the penny dissolves.) B. Write a balanced chemical reaction for zinc and hydrochloric acid. C. Use stoichiometry to calculate the mass of zinc in the penny. D. Determine the percent zinc (by mass) in the penny.
