Given that the density of water is 0.975 g/ml and that 171 g of sucrose (molar mass: 342.30 g/mol) is dissolved in 512.85 ml of water at 80°c, what is the molality of this solution?

1 molal

Explanation:

Molality of a solution is defined as the number of moles of solute dissolved per kg of the solvent.

where,

n= moles of solute

  = weight of solvent in g

Putting in the values we get:

Thus molality of solution will be 1 molal.

they both have a y in them

elements

explanation:

yes the other ones are right just show me a pic of ur face cuz u look hot
