Question

How many grams are there in 3.30 x 1023 molecules of N2I6?

Answer 1

Answer:

1mole N2I6 = 789.44022g N2I6

1mole N2I6 = 6.022 x 1023 molecules N2I6

1) Convert molecules to moles.

3.3 x 1023 molecules N2I6 x (1mol N2I6/6.022 x 1023 molecules N2I6) = 0.55mol* N2I6

* Rounded to two significant figures.

2) Convert moles to mass in grams.

0.55mol N2I6 x (789.44022g N2I6/1mol N2I6 = 430g* N2I6

*Rounded to two significant figures.
