A mass of 134 g of manganese dibromide is dissolved in 225 g of water. What is the molality of the solution? Chemistry Solutions Molality 1 Answer anor277 Apr 24, 2017 #"Molality"~=2.8*mol*kg^-1# Explanation: By definition, #"molality"="moles of solute"/"kilograms of solvent"#, and thus for this scenario, we work out the quotient, #"Molality"=((134*g)/(214.75*g*mol^-1))/(225*gxx10^-3*kg*g^-1)=??*mol*kg^-1# Answer link Related questions How do molality and molarity differ?
