I think that it is D because the higher the molecular mass, the higher it's boiling point. I hope that helped:) Bye!
Answer:
tha mass of magnesium nitrate is 592g
Explanation:
from a balanced chemical equation
2HNO3 + Mg(OH)2→ Mg(NO3)2 + 2H2O
2 mol of nitric acid is equivalent to 1 mol of magnesium nitrate. then 8 mol of nitric acid will be equivalent to 4 mol of magnesium nitrate.

Answer:
0.779 moles.
Explanation:
Mass of chlorine/number of moles = molar mass of chlorine.
Molar mass of chlorine = (35.5*2)
= 71 g/mol.
Mass = 55.3 g of chlorine.
Number of moles = 55.3/71
= 0.779 moles.
