You are provided with a 250 mL volumetric flask, deionized water, and solid NaOH. How much NaOH should be weighed out in order to make 250. mL of 0.100 M solution?
Homework Answers
Molarity = weight of solute *1000/Gram molar mass of solute * volume of solution in ml
0.1 = weight of solute*1000/40*250
Weight of solute = 40*250*0.1/1000
= 1gm
weight of NaOH is 1gm
