How do you calculate percent recovery?
I have this info:
Weight of sample used: 0.198g
Actual weight of sample: 0.325g
Other info needed?
What you have posted is confusing. What do you mean by "actual weight of sample?" Is that different than the weight of sample used? I suspect you meant actual weight of recovered sample was 0.325. What was the recovered sample?
%recovery = [Actual mass recovered/theoretical mass]x 100.
If you will post the entire problem I expect we can help.

To calculate percent recovery, you need two pieces of information: the actual weight of the recovered sample and the theoretical weight of the sample you initially used.
In your case, you mentioned the weight of the sample used was 0.198g, but it's unclear what you mean by the "actual weight of sample." Typically, the actual weight of the recovered sample refers to the weight of the substance you obtained after performing a process, such as a chemical reaction or separation. If this is what you meant, and the actual weight of the recovered sample is 0.325g, then you have the necessary information.
To calculate percent recovery, you can use the formula:
% recovery = (actual weight of recovered sample / theoretical weight of sample) x 100
In this case, you can substitute the actual weight of the recovered sample as 0.325g and the theoretical weight of the initial sample as 0.198g:
% recovery = (0.325g / 0.198g) x 100
Now you can divide 0.325 by 0.198 and then multiply by 100 to find the percent recovery.
