I haven't taken chemistry in over 3 years so I have forgotten a lot of the very basic concepts (even while understanding the higher level stuff) and am having problems with this simple thing! Please help :(. Question 1- At 20°C, a 2.32 M aqueous solution of ammonium chloride has a density of 1.0344 g/mL What is the molality of ammonium chloride in the solution? The formula weight of NH4Cl is 53.5 g/mol. I don't think I have to use temperature here. I know how to calculate molality when im given how many grams are in the solution but the way this one is worded im confused. Not looking for the answer, just a little help on where to start.
