How many moles are in 1.204 x 10^24 molecules of Bromine

2.2876e+24 or 2.2876000000000000000000000000 (same thing)

Explanation:

First we can do the exponents first

When there is an exponent on top of a number, it means that we need to multiply that number by the amount that the exponent says by itself.

10 × 10 × 10 × 10 × 10 × 10 × 10 × 10 × 10 × 10 × 10 × 10 × 10 × 10 × 10 × 10 × 10 × 10 × 10 × 10 × 10 × 10 × 10 × 10 =

1E24 or 1,000,000,000,000,000,000,000,000

1,000,000,000,000,000,000,000,000 × 1.204 =

2.2876e+24 or

2.2876000000000000000000000000

~ 2.2876 r 2.288 or 2.28, or 2.3

Depends on how much you want to round it up to.
