Calculate the molarity for each solution : a) 1.5 l of solution containing 2.5 mol of sugarb) 0.15 mol of h2so4 in 400 cm³ solutionc) 0.12 g of naoh in 325 ml of solution

a) c = n/V = 2.5 / 1.5 = 1.7 moles/dm3

b) c = n/V = 0.15 / 0.4 = 0.4 moles/dm3

c) n = m/M = 0.12 / 39.997 = 0.003 moles. c = n/V = 0.003 / 0.325 = 0.009 moles/dm3
