How would you prepare a solution of NaOH of 0.100M?
M stands for Molarity. Molarity is a measure of concentration and the units of molarity are mols per dm^3. The molecular weight of NaOH is around 40 g/mol so in order to make a litre solution of concentration 1M it would be necessary to dissolve 40g in 1 litre. To make 1 litre of 0.100 M solution of NaOH dissolve 4g of NaOH in 1 litre of water. The equation governing this is shown below Molarity = mols/vol where vol is in litres There is no need to titrate this in order to find the concentration usually a titration is carried out with a known standard against an unknown to find the concentration. Usually one tries to avoid using sodium hydroxide in a burette as strong base tends to etch glass rendering accurate glassware inaccurate if not washed immediately.
