the amount of moles of Na₂CO₃ required = 0.446 moles to find out the mass of Na₂CO₃ required, we need to find out its molar mass. Molar mass is the mass of one mole of the element / compound. molar masses of the elements are as follows; Na - 23 g/mol C - 12 g/mol O - 16 g/mol Molar mass of Na₂CO₃ can be calculated as follows; (Na *2 ) + C + (O *3) (23*2) + 12 + (16*3) = 46 + 12 + 48 =106 g/mol 1 mol of Na₂CO₃ weighs - 106 g Therefore 0.446 mol = 106 g/mol * 0.446 mol = 47.27g
