Question

What is the final concentration (m) of a solution prepared by diluting 50.0 ml of a 6.00 m kcl solution to a volume of 1.00 l?

Answer 1

M1V1=M2V2, M - molarity, V- volume, it should be in the same units

So we take 1.00L =1000 mL

6.00*50.0 mL=M2*1000mL

M2=(6.00*50.0 mL)/1000mL=300/1000=0.300 M
