Question

Calculate the number of grams in: 2.93moles NaOH.

Answer 1

40-gram Weight

Step-by-step explanation:

Answer 2

We have that the molar mass of NaOH is 40 g/mol (you can calculate this using the periodic table), so the conversion from moles to grams would be:

`2.93\text{ moles NaOH}\cdot\frac{40\text{ g NaOH}}{1\text{ mol NaOH}}=117.2\text{ g NaOH}\approx117\text{ g NaOH.}`

There are 117 g of NaOH in 2.93 moles.
