Answer to Question #98444 in Organic Chemistry for david

Question

)If 300.0 ml of 4.5 m HBR solution is diluted to a total volume of 55.0 ml, what is the new concentration?

Answer 1

m₁V₁ = m₂V₂

here m₁ being the initial molality, m₂ being the final molality, V₁ being the initial volume and V₂ being the final volume

m₁= 4.5m, m₂=?, V₁= 300 ml, V₂=55 ml

putting all above in the equation gives:

4.5 * 300 = m₂ * 55

m₂= 24.54 m
