DETERMINE THE MASS 1.22 mol sodium

28.06g

Explanation:

number of moles = Reacting mass

Molar mass

number of moles = 1.22mol

Molar mass of sodium= 23g/mol

So therefore, 1.22 = Reacting mass

23

Reacting mass = 23×1.22

Reacting mass = 28.06g

i think it is d. e because the next one is igneous.

the answer is 1260

you spend 7 hours in school for 1 school day with 5 school days in 1 school week with 36 school weeks in a school year.

7*5*36= 1260 it's all about multiplying
