Answer:
The answer to your question is 2.84 M
Explanation:
Data
mass of MgO = 57.3 g
volume of the solution = 500 ml
Process
1.- Calculate the molar mass of MgO
MgO = 24.3 + 16 = 40.3 g
2.- Calculate the moles of MgO
40.3 g MgO ----------------- 1 mol
57.3 g MgO ----------------- x
x = (57.3 x 1) / 40.3
x = 1.42 moles
3.- Calculate the Molarity
Molarity = moles / volume (l)
Volume = 0.5 liters
-Substitution
Molarity = 1.42 / 0.5
-Result
Molarity = 2.84
