Question

Calculate the no of moles n amount in g of NaOH in 250cm^3 of a 0.100M NaOH soln

Answer 1

Number of moles of NaOH in 250cm^3  = 0.1 * 250/1000

                                                                  = 0.025

Mass of NaOH in 250cm^3    = Number of moles * molar mass of NaOH

                                                = 0.025 * 40

                                                = 1
