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.

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.

answers: to make sure that all of the broken pieces of tablet were added to the water, to allow for fair comparison of all three trials, with different particle sizes to avoid experimental error
