1.20 M is 1.2 moles in 1 liter of solution (by definition)
in 0.250 liter you have:
0.25 * 1.2 = 0.3 mol

basically undergo in strategies the easy relationship. A a million M answer additionally skill a million mmol according to mL. you have 250 mL, and the concentration is a million.2 M, so what number mmoles is that? Or, a a million.20 M answer skill a million.2 moles in a single liter, and you in basic terms have a million/4 liter.

M=mole/L
change ml to L which is .25L
mole=0.3

Molarity X Volume (in L) give you moles of solute. You should be able to get there with that.

well molarity is equal to number of moles divided by liters. let's use algebra to figure it out! =]
250mL=0.25L
x/0.25=1.2
x=0.3
and so there are 0.3 moles.
btw you wrote NaCL. it's NaCl. proper capitalization is important!
