#"Molarity"=0.264*mol*L^-1#

Explanation:

#"Molarity"="Moles of solute"/"Volume of solution"#

And thus #"Molarity"=((9.63*g)/(36.46*g*mol^-1))/(1.5*L)=0.264*mol*L^-1.#

Note that our dimensions our consistent. We wanted an answer with units of concentrations, i.e. #mol*L^-1#, and the given quotient gave us an answer with such units. It is all too easy to multiply when you should divide, and vice versa.

What is #pH# of this solution?
