This is exactly why Chemistry and Algebra should not mix.

Ultrilliam · Answer

tmw you flatout tell them what it is and their like "nope"

Vocaloid · Answer

you have the right idea

idk if you have learned this but in chemistry we use significant figures so the answer would have the same number of decimal points as the original number (7.55×1014)

Vocaloid · Answer

so it would just be 5.00e-19
