Answer 2

first thing first what do you think it is

Answer 3

(oh thank god finally some help!!)

and honestly i have no idea, but if I where to pick one id have to say 25 atoms of mercury(?) idk it sounds like it has the most.......

@micahm

Answer 4

Are you just saying that because it has the largest number, or did you just take a guess?

Remember, you can use avogadro's number to convert from atoms to moles, and then the molar mass to get grams of whatever atom you have.

Answer 5

\(\sf 25~atoms \times \frac{1~mol}{6.022 \times 10^{23}~atoms}(\frac{grams}{mol})_{of~ mercury}\)

Answer 6

@abb0t so then it not the highest but _____________ or the smallest ?

Answer 13

if you can't find the answer go with you first guess

Answer 14

Don't guess. Rule out the answers with atoms, because they will have incredibly small masses. It is one of the two choices that are given in moles. For each one, convert from moles to mass to be able to determine which mass is higher.

@pooja195 thanks !!

Why the heck did you tag me more than once? Clearly, I was not here.
