Acertain solution has a molarity of m = 6.39 mol/l and has a volume of v =0.550 l what is the value of n

n = 3.49 mol

Molarity = moles/litres or c = n/V

n = Vc  = 0.550 L × (6.39 mol/1 L) = 3.49 mol

sorry i was late, but i don't know what assignment your talking about, i'm in flvs as well, im in earth space science. but u are behind pace bc every class should be in the 3's or 4'
