Answer:

b) 3.000 mol S

Explanation:

using Avogadro's constant

1 mol = 6.02 × 10^23 atoms

we need to find the number of moles for 1.806 × 10^24

x = 1.806 × 10^24

putting it together we now have:

1 mol = 6.02 × 10^23 atoms

x = 1.806 × 10^24

cross multiply

6.02 × 10^23 x = 1.806 × 10^24

divide both sides by 6.02 × 10^23

x = (1.806 × 10^24) ÷ (6.02 × 10^23) = 3 mol

What is the percent composition of hydrogen in NH4HCO3?

Readme [11.4K]

To find the Percent Composition of an atom, you use this formula:
Mass of element in the compound you're studying on ( in this case it's 5 since there is 5 Hydrogens) over the mass of the compound (which is here 79), Multiplied by 100 since you want a percent.
So we get:
$\frac{5}{79} * 100$
So you get about:
$0.063 * 100$
$6.3$

So, the percent composition of Hydrogen in NH4HCO3 is 6.3%

Hope this Helps! :D
