Q1:

Find the volume in ft3

of 1.0 mole of an ideal gas

at −25°C and 710 torr.

Q2:

A mixture containing 13.5 g of oxygen and 60.4 g

of N2 exerts a pressure of 2.13 atm at 25°C. What is the volume of the container, and

what are the partial pressures of each gas?

Q3:

Suppose that 270 mL of CO2 at 1.03 atm and 25°C

is produced by this reaction. Assuming that an excess of hydrochloric acid was pres-

ent, how many grams of sodium bicarbonate were used?

Q4:

SO2 can be generated in the laboratory by heating

ZnS with O2. (The other product is zinc oxide.) If 14.5 L of oxygen at STP is reacted

with excess zinc sulfi de, what volume of SO2 at STP is generated?

Q5:

HCl(g) reacts with ammonia gas, NH3(g), to form solid

ammonium chloride. If a sample of ammonia occupying

250 mL at 21°C and a pressure of 140 torr is allowed to

react with excess HCl, what mass of NH4Cl will form?

Q6:

Hydrogen gas is generated when acids come into contact

with certain metals. When excess hydrochloric acid reacts

with 2.5 g of Zn (the metal product is Zn2+), what volume

of hydrogen gas is collected at a pressure of 0.93 atm and a

temperature of 22°C?
