4a) Calculate the molar concentration of a solution containing 120g of NaOH per dm3.
b)Calculate the molar concentration of a solution containing 5.00g of NaOH in 250cm3.
c)Calculate the mass of NaOH dissolved in 25.0cm3 of a solution of concentraion 5mol dm-3.
5) HCl(aq) + NaOH(aq) --> NaCl(aq) + H20(l)
a)For the reaction above, calculate the volume of 0.5000 mold dm-3 HCl required to neutralise exactly 15.0cm3 of 0.750 mol dm-3
b)Calculate the concentration of a NaOH solution when 25.0cm3 of the solution is neutralised by 17.5cm3 of 0.350 mol dm-3 HCl.
A step by step guide would be very much appreciated - my teacher doesn't explain anything, and I don't have the time to see her (before anyone has a bender
)
Thanks
