Question

when 1.00 g of solid k dissociates in 500.0 g of water in a coffee cup calorimeter, the temperature rises from 21.3 °c to 23.5 °c.
$c_{sol} = 4.18 \\, \text{j/g °c}$
what is the mass of the solution?
$\text{mass}_{sol} = ? \\, \text{g}$

Explanation:

Step1: Identify masses of solute and solvent

Mass of solute (K) is 1.00 g, mass of solvent (water) is 500.0 g.

Step2: Calculate mass of solution

Mass of solution = mass of solute + mass of solvent = 1.00 g + 500.0 g = 501.0 g.

Answer:

501.0
