Answer:
C
Explanation:
We know that the molar mass of KOH is 56 gmol-1
Molar mass of Mg(OH)2 is 58.31 g/mol
Now; the balanced reaction equation is; MgCl2 + 2KOH → Mg(OH)2 + 2KCI
Hence;
2 moles of KOH yields 1 mole of Mg(OH)2
4 moles of KOH yields;
4 moles of KOH/1 mol * 1 mole Mg(OH)2 /2 moles KOH * 58.31 g Mg(OH)2 / 1 mole Mg(OH)2
So option c is correct
False because a compound is one or more elements
