Question 1

A mixture of 10.0 g of Ne and 10.0 g Ar have a total pressure of 1.6 bar. What is the partial pressure of Ne?
◦ 0.54 bar
◦ 1.1 bar
◦ 0.40 bar
◦ 1.3 bar
◦ 0.80 bar

Question 2

The following reaction is used to generate hydrogen gas in the laboratory. If 243 mL of gas is collected at 25 °C and has a total pressure of 0.9933 bar, what mass of hydrogen is produced? A possibly useful table of water vapour pressures is provided below.

Mg(s) + 2HCl(aq) → MgCl2(aq) + H2(g) T (°C)P (bar)
200.023398
250.031704
300.042477

◦ 0.0196 g H2
◦ 0.0190 g H2
◦ 0.0449 g H2
◦ 0.0144 g H2
◦ 0.0717 g H2
