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
