. Which of the following correctly identifies the number of each element involved in the chemical formula (NH4)2CO3

a. N:2 H:4 C:3 O:3

b. N:2 H:4 C:1 O:3

c. N:2 H:8 C:0 O:3

d. N:2 H:8 C:1 O:3

In order to determine percent composition of the elements in a compound, the molar mass (MM) of each element is divided by the MM of the compound and multiplied by 100.

% composition of element=MM of elementMM of compound×100

The molar mass of ammonium carbonate ((NH4)2CO3) is 96.086 g/mol. (Determined by multiplying the subscripts of each element times its MM using its atomic mass in g/mol on the periodic table.)

Step-by-step explanation:

Hope this helps, If it did, then I would really appreciate it if you gave me Brainliest, I only need one more to rank up and it has taken forever to get to where I am currently. Thanks.

answer is d-29

step-by-step explanation:

since you didn't include the picture, i can give you the description so you know how to pick the correct answer. the third quartile of a data is always shown in a box plot. in the middle of your graph should be a box. the third quartile is the value that goes with the far right edge of the box.
