Calculate the molarity of 29.25 g of NaCl dissolved in 700ml of total solution in moles per litre.

I know that 1 mol of salt is 57 g so 29.25 g of salt is ~0.51 mol...

But then what?

Is the answer ~0.35 mol/700L ? I cross multiplied.

Thanks

x moles------------>700mL

y moles------------>1000mL

Daniel.

P.S."y" is the one you're interested in.

i got ~0.51 moles by dividing 29.25 by 56.5, the i cross multiplied knowing x.
