2 Na + Cl ---> 2NaCl
Greeley [361]

Answer:

1. d. 84g

2. c. 77.4%

Explanation:

1. Based on the reaction 2 moles of Na produce 2 moles of NaCl.

The moles of Na (22.99g/mol) in 33g are:

33g * (1mol / 22.99g) = 1.435 moles Na = 1.435 moles NaCl must be produced.

The mass of NaCl is (Molar mass: 58.44g/mol):

1.435moles * (58.44g / mol) = 84g

d. 84g

2. Percent yield is defined as 100 times the ratio between actual yield (65g) and theoretical yield (84g). The percent yield is:

65g / 84g * 100 =
