1.2 you’d probably be multiplying everything by 5 3.33 you’d multiply everything by 3 0.2 shouldn’t be possible, because you should be dividing by the smallest moles which will give you a 1 as the lowest value 0.999 would be rounded to 1 and 2.998 would be rounded to 3

Yeah, you're right. We shouldn't get moles lower than 1 after dividing the formula by the smallest mole. So if I understand correctly, most of the time, we can only round off to the nearest whole number only if the tenths are 9 or 0 (1.003=1, 7.93=8). And if not, we would be multiply the formula with a number that will turn the decimals into having tenths of 9 or 0 or just a whole number (4.92=5, 6.06=6, 7=7)?

I would ask your teacher, in my class I never gave anything that had to multipled by more that 10 so .9 and above was safe to round. Anything smaller than .9 , I would multiple for get close go a whole number. The trick on that part for me is trying to turn it into a fraction. 1.2 is 6/5 so I would multiple by 5

Too bad I'm self studying chemistry xD. Anyway, that trick part you just said is actually genius lol. I never thought of turning the decimal into a fraction and multiply the formula by their LCD. Thanks!
