Assuming the question refers to LiCl (Lithium chloride) which has a molecular weight 42.39. <span>Avogadro's constant states there are 6.022 141 79x1023 molecules per mole </span><span>9.34 g LiCl is 9.34/42.39 mole (0.220 mole) LiCl </span>
<span>The number of molecules is therefore 6.022 141 79x1023x 0.220 =1.326x1023 molecules</span>

Answer:</h2><h2>
The percentage of the family’s total annual electricity that is used to run the two air conditioners for the three summer months = 19.4 %</h2>
Explanation:
Average electricity consumed per month = 900 kWh
The family cools their house for three months during the summer with two window-unit air conditioners
The power consumed by one window-unit air conditioners = 350 kWh
The power consumed by two window-unit air conditioners = 350(2) = 700 kWh
Power consumed for two air conditioners for the three summer months = 700 (3) = 2100 kWh
Total power consumed for 1 year = 900 (12) = 10800kWh
The percentage of the family’s total annual electricity that is used to run the two air conditioners for the three summer months =
= 19.4 %
