If there is 5 liters of a 3 m solution, how many moles does the solution contain?

V (volume) = 5l

c (molar concentration or molarity) = 3 M = 1 mol/l

c = n/V, where n is the number of moles or amount of substance

So: n = c * V = 3 mol/l * 5l = 15 moles

correct answer: false

while planning water activities, it is very important to consider the weather, because if we do not plan and are going for a surf, then it might be that the hurricane came and drown us or may carry us to long distance from where we can not come back. there are many reasons to take information about the weather when we are planning any water activities.

hence, the correct answer would be false.
