Answer:
Molarity= number of moles / volume of solution in litre .So, first we find no. Of moles ,that is no. of mole = given mass / molar mass. Molar mass of Na2CO3 =23×2+12+3×16=106 and here volume is given in ml,so we multiply 1000 to above formula ,molarity(M)= ( no. of moles/volume of solution in ml )×1000. So, M=((2.62/106)/600)×1000=24.71
