How many molecules are in 0.54 moles of NaBr?

There are 3,5 x 10 e 23 molecules in 0.54 moles of NaBr.

Explanation:

We use Avogadro's number, according to which in 1 mole of any substance there are 6,023 x 10 e23 particles (example: atoms, molecules). We calculate the number of molecules according to the following simple three rule:

1 mol NaBr6,023 x 10 e23 molecules

0,54mol NaBrx= (0,54mol NaBr x 6,023 x 10 e23 molecules)/1 mol NaBr

x=3,5 x 10 e 23 molecules

a. possible errors

d. new questions

explanation:

predictions and planning happen before. a summery comes after. errors you get after investigation and new questions propose what you can look for in the future.
