Answer:
4 moles of MgCl2 will produce 4 moles of MgSO4 when reacted with excess K2SO4.
Step-by-step explanation:
To determine the moles of MgSO4 produced when 4 moles of MgCl2 react with excess K2SO4, you need to consider the stoichiometry of the balanced chemical equation between MgCl2 and MgSO4. Let's assume the balanced equation is:
MgCl2 + K2SO4 -> MgSO4 + 2 KCl
From this equation, you can see that 1 mole of MgCl2 reacts to produce 1 mole of MgSO4.
Given that you have 4 moles of MgCl2:
4 moles of MgCl2 will produce 4 moles of MgSO4.
So, 4 moles of MgCl2 will produce 4 moles of MgSO4 when reacted with excess K2SO4.
