What is the Molarity of a solution prepared by dissolving 74.5 g of NaOH in water to make 1.50 L of solution? A. 1.24M
B. 40.0M
C. 49.6M
D. 1.86M

74.5 g of NaOH is dissolved in water to 1.50L of Solution .

We have been asked to find the molarity of solution

Formula to calculate Molarity

First Let's find the Molar Mass of NaOH

Put the given value we get

Now calculating the molarity of given solution

So, the molarity of the solution is 1.24M

Option (A) is your correct answer.

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z

answer

the correct answer would be b. amelia, because the particals of gas move really fast (charged particals) and gas also has a lot of room (particals move independently) so the only answer that has both of those is amelia's.
