Update now 2.UFAT#27] At standard temperature and pressure (zero celsius and one atmosphere), one mole of gas will occupy a volume of 22.4 liters (about eleven two-liter bottles) How many grams of tin, Sn, would be required to produce 22.4 L (1.00 mol) of hydrogen gas, using the reaction with hydrochloric acid shown below? (The molar mass of Sn is 118.7) a) 216 g Sn b) 108 g Sn c) 153 g Sn d) 59.4 g Sn

Explanation / Answer

answer : d) 59.4 g

Sn      +     4 HCl     ---------------> SnCl4   +    2 H2

1 mol Sn -----------> 2 mol H2

   ??            -----------> 1 mol H2

moles of Sn = 0.50 mol

mass of Sn = 0.50 x 118.7

mass of tin = 59.4 g
