# Chem Titrations Calculations help? watch

1. Hey, having some trouble with my assessed homework.

I think i've done this correct:

a) 2dm3 of 0.05 M HCL, calculate the number of moles

0.05 x 2 = 0.10 moles.

but how would you do 25cm3 of 0.01 M NaOH? because the units are cm3.....

and secondly, calculate the concentration of the following:
a)i) 0.400 moles of HCL in 2.00 Litres of solution
ii) cm3 of solution

Thanks

2 things to remember:

1. To convert from to you divide by 1000
2. is the same as a litre
