Answer: 1.58 x 
Explanation:
1 mole of magnesium chloride has a mass of 95.211 g and contains 6.022⋅
formula units of magnesium chloride, you can say that,
25.0 g x (6.022 x
form units MgCl2) /95.211 = 1.58 x 
Chlorine gas, or dichlorine, is composed of 2 chlorine atoms and has a molar mass of 70.96, or about 71 g. So the answer is the molar mass is 71 g.
Hope this helps!
Answer: 1. 2.7 moles of ammonia are formed
2. 12.0 moles of hydrogen are required
3. 2.0 moles of nitrogen are required
Explanation:
The balanced chemical equation is:

According to stoichiometry:
3 moles of hydrogen form = 2 moles of ammonia
Thus 4.0 moles of hydrogen form =
of ammonia
According to stoichiometry:
2 moles of ammonia are formed by = 3 moles of hydrogen
Thus 8.0 moles of ammonia are formed by =
of hydrogen
According to stoichiometry:
3 moles of hydrogen react with = 1 mole of nitrogen
Thus 6.0 moles of hydrogen react with =
of nitrogen
