Answer:

386.75 grams

Step-by-step explanation:

You can use dimensional analysis to help you solve for this question

1. set up a proportion

x grams

4.25 mol x x mole

2. to find the amount of grams/mol that are in NiS we find the gram formula mass (mass of all the atomic masses of each element)

Ni- 59 grams

S- 32 grams

add these together and you get 91 g/mol

3. now plug in the values and multiply across

91 grams

4.25 mol x 1 mole

when you multiply across this is equal to 386.75 grams
