Answer:
427.5g
Explanation:
Given parameters:
Number of moles = 4.5moles
Unknown:
Mass of MgCl₂ = ?
Solution:
To solve this problem;
Mass = number of moles x molar mass
Molar mass of MgCl₂ = 24 + 2(35.5) = 95g/mol
Mass = 4.5 x 95 = 427.5g
Answer:
2 reactants 2 products.
this is a balanced chemical equation. That means the number of chlorine before the arrow will be the same after the arrow
