Question

You wish to prepare 202 grams of 12.5% (w/w) . Assume that the density of water is 1.00 g/mL.

QUESTION:

You will need _________ grams of sodium iodide and _______ mL of water.

Answer 1

Answer #1

Answer:-

This question is solved by using simple formula of mass/mass percent concentration and the firstly mass of solute is calculated then mass of water.

The answer is given in tha image,

Answer:- mass of solution = 2029. concentration = 12.57.(Ww) so, loog solution = 12.5g Nai 202 g solution = 12.5 x2029 Nal =
