Question

How many grams of NaOH are present in 3.1 moles of NaOH. (The molar mass of NaOH is 39.997 grams/mol)



If you are unsure how to convert moles to grams, please see the example problem linked HERE.

a
43.10 grams of NaOH
b
0.078 grams of NaOH
c
12.90 grams of NaOH
d
123.99 grams of NaOH

Answer 1

The correct answer is:

c) 12.90 grams of NaOH

To calculate the number of grams of NaOH in 3.1 moles, you can use the molar mass of NaOH:

3.1 moles * 39.997 grams/mol = 123.99 grams

So, there are 123.99 grams of NaOH in 3.1 moles.
