(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

I'm having difficulties figuring out how many significant figures to report for several caluclations in my lab report. As it is a report, there are no specific problem statements.

2. Relevant equations

No equations, but there is a rule I was told: when dividing/multiplying I was told to use the "least precise value determines the number" of sig figs.

3. The attempt at a solution

For example: One of my calculations for percent error is as follows |30mL-22.7068mL|/22.7068(g/mol) * (100) = 32.1190%.

I know that: 30 is 1 sigfig; 22.7068 is 6 sigfigs; 100 is 1 sigfig.

Therefore, according to the rule, I believe that the least precise value is 1 significant figure. So, should I report this percent with 1 significant figure? I'm not sure how I would do that...round down perhaps to 30%?

Thank you!
