Question

The molar mass of hydrogen fluoride, HF, is 20.0 g/mol. If 17.0 grams of HF are dissolved in water
to give 200.0 mL of solution, what is the molarity of this solution?

Answer 1

mols = grams/molar mass = ?. Then
M = mols/L solution.

Answer 2

i don't know which numbers to plug in where. this is what i was given in my intro to chem class and i am totally lost.

Answer 3

would it be 17/20.0=?

Answer 4

4.25
