1. calculate the molality of a solution prepared by dissolving 175 g of kno3 in 750 g of water. show you work. i know that molality=moles of solute/kilograms of solvent, but i do not understand how to get this. !

Molar mass KNO₃ = 101.1032 g/mol
Mass of solute = 175 g
Volume = 750 ML in liters : 750 / 1000 = 0.75 L
Number of moles:
n = mass of solute / molar mass
n = 175 / 101.1032
n = 1.7309 moles
Molarity :
M = moles of solute / volume in liters
M = 1.7309 / 0.75
= 2.307 M
hope this helps!
