Question

If you have 35 moles of sodium hydroxide (NaOH) in a 5000 mL solution, what is the concentration of the NaOH in the solution?

Answer 1

7 mol.dm^3

Step-by-step explanation:

formula for calculating concentration: C = n/v

Start by changing 5000ml solution to dm^3 because volume is in dm^3

1 ml = 1cm^3

then from a cm^3 to dm^3 you divide by 1000

5000ml = 5000cm^3

5000÷1000= 5dm^3

c = n/v

= 35/5

= 7mol.dm^3
