Question about GC calculations

Members don't see this ad.

I'm going through the Destroyer GC portion, and I'm wondering how you all are calculating these numbers without a calculator?

For example, I just finished a limiting reagent problem that asked how much product would be produced. The calculation to find the moles ended up looking like (76 g/152 g). But how would we calculate this without a calculator? Wouldn't our numbers be off if we tried to estimate?

Thank you for reading! Any feedback is appreciated 🙂

on the real deal, an answer such as 76/152 will be one of the multiple choices to pick.... with destroyer, I would just use the calculator OR... practice doing long division (for math practice for QR)

I don't have the destroyer but, from someone who recently took the test(last monday) they told me that a lot of the calculations on the test didn't require a lot of number crunching(cancellations or easy numbers) and in fact a lot of them were left in the set up form and not solved completely.

Thanks for the responses! You both give me one less thing to worry about! 🙂

Just reduce 76/152 to 19/38, if needed.

how about 1/2
