answer accuracy

[leediane0916]

When I solve problems I don’t round until the very end and keep all my sigfigs but sometimes the answer I get is 0.01-0.02 digits different from the one in the solution manual. Will this be a big problem on the homework/test?

I would suggest asking your TA, because it depends on what the person grading your work thinks. Also, I believe the solution manual's answers assume that you round throughout your working rather than rounding at the end - so for each calculation you perform, you round to the correct number of sig figs before moving on to the next calculation.

I would ask your TA, because they will be grading our homework and test, therefore some of them are more strict on sig figs than others.

This typically is not a problem as most periodic tables have slightly different molar masses so being .01 or .02 of is to be expected.

I don't know about you but my TA said that as long as it is within .1 of the the correct answer you should be fine for the tests.
