Question

The molar mass (molecular weight) of NaOH is 40.0. How many grams of NaOH will be
required to prepare 0.01 NaOH solution
A) 40.0 g B) 4.0 g C) 0.40 g D) 0.04 g

Answer 1

Your making a 0.01 Molar NaOH solution?

Answer 2

If so it would be C, as Mass = Molar Mass * Moles
So 40 * 0.01 = 0.4 :)

Answer 3

no but the answer is .04!

Answer 4

that is D

Answer 5

@C9H8O4 is right. C is the correct answer.
1 mol = 40 gram
0.01 mol = 0.01*40 = 0.4 gram.

Answer 6

oh ok.
