Hi I just wanted to verify a few answers to chem questions I'm working on. Was wondering if anyone could help?
1. Calculate the molar concentration of 2.34g of lithium hydroxide, LiOH disolved in water to make 750ml of solution.
My answer was CLiOH = 0.133 mol/L
nLiOH = 2.34g/24g/mol = 0.0975 mol
MLiOH = 24g/mol
CLiOH = 0.1 mol/.750 ml = 0.133 mol/L
2.If 200g of glucose is present in 500ml solution, what is the w/v percentage?
my answer was 40%
200g/500ml x 100%
Were these ok?
1 answer
They are ok.
