Calculate the mole ratio of 240 g calcium and 240 g of magnesium. (Ca = 40 u; Mg = 24 u)

Molar mass of calcium, Ca = 40g

Given Mass of the calcium = 240g


As we know that, Number of moles = mass of an element/molar mass of an element


Hence Number of moles of Calcium = 240g/40g = 6 moles.


Molar mass of magnesium, Mg = 24g


Given Mass of the magnesium, Mg = 240g


As we know that, Number of moles = mass of an element/molar mass of an element


Hence Number of moles of magnesium = 240g/24g = 10 moles.


From above calculation, the molar ratio can be inferred - 6:10 = 3:5
