The molar mass of sodium carbonate is 105.99 g/mol.
100 cm x 2 m = 200 cm
200 cm x (1 L/1000 cm) = 0.2 L
0.2 L x (2 mol/L) = 0.4 mol
0.4 mol x (1 mole Na2CO3/2 mol) = 0.2 moles Na2CO3
100 cm x 2 m = 200 cm
200 cm x (1 L/1000 cm) = 0.2 L
0.2 L x (2 mol/L) = 0.4 mol
0.4 mol x (1 mole Na2CO3/2 mol) = 0.2 moles Na2CO3
