What is the mass percentage of H in hydrochlorothiazide, C₇H₈ClN₃O₄S₂? Provide an answer to two decimal places

2.71%

Explanation:

hey dog.

you confused?

I GOT YOU.

whip out that PERIODIC TABLE MAN THE PERIODIC TABLE WILL SAVE YOUR LIFE ALL DAY! someone will walk up to you all mean and youll be like, "what, you tryna mug me?" WHAM YOU WHIP OUT THAT PERIODIC TABLE AND YOU MESS EM UP! JUST LIKE WE ARE GONNA MESS UP HYDROCHLOROTHIAZIDE RIGHT NOW cuz it thinks its so cool with that name but then we're gonna be like nu-uh we gotcha we are looking for H hydrogen.

look at this bro im gonna look at the C carbon part of the periodic table it looks like this

6

C

12.011

dog... look at that number underneath the letter... what is that? thats ATOMIC MASS bro thats ATOMIC MASS and we are looking for the MASS PERCENTAGE isnt that right? ok we are looking for C7H8ClN3O4S2

so we know that 12.011 is carbon so lets multiply (7 x 12.011) because in this compound/substance there are seven carbons. we get 84.077

now lets do the same thing with hydrogen, remember look at the periodic table and we see the mass for hydrogen is 1.008 so multiply that by 8 because theres 8 hydrogens in this compound and we get 8.064

do the same for the rest of the elements: chlorine, nitrogen, oxygen, sulfur add it all up and we get: 297.728 amu (atomic mass units)

ok so now we are looking for mass percentage of H so remember we found that it was 8.064 amu of hydrogen in this compound?

so do this: 8.064 / 297.728

we get 0.027085124... multiply this by 100 because we are looking for PERCENTAGE

and we get 2.708 so round to two decimal places we get 2.71 %

AWESOME SWAG

your picture is not part of the scientific method.

mention the spill to the teacher clean the area and throw the broken pieces away
