An aqueous solution of glucose is made by disolving 8.75 g of glucose in 100 mL of water. Calculate molarity, molality and the mole fraction

Answer 1

M = mols/L. You get mols by grams/molar mass.

Now that you have mols, you can calculate m.
m = mols/kg solvent.

for X.
You have mols glucose.
Find mols H2O = grams/molar mass
Then total mols = mols glucose+mols H2O
Xglucose = mols glucose/total mols.
Post your work if you get stuck.
