Answer:
3.990225 grams
Explanation:
Remember: Morality = Moles/Liters
And you are given:
100 mL and 0.25
what you want:
Grams
SOOOO.....
convert the 100 ml to L
100 / 1000 = .1 L
now that you have Liters and Morality put it into the equation
0.25 M = Moles/ .1 L
0.25 * .1 L = .025 moles
now you take this and turn it into grams
0.025 moles / molar mass = grams
0.025 moles / 159.609 g = 3.990225 grams
