b. 4.0 g of KOH in 2.0 L of solution
c. 5.85 g NaCl in 400. mL of solution

Answer 1

Molarity = moles / volume

a. 2mol/4L

b. (4g/molar mass of KOH)/2L

c. (5.85g/molar mass of NaCl)/0.4L

units of molarity is M (or mol/L)

Answer 2

thanks

Answer 3

just make sure your volume is in Liters

Answer 4

but allix couldnt have been more clear.

Answer 5

ok
