When performing calculations in Chemistry, you should always carry unrounded intermediate values then round the final answer to the correct number of significant figures. In the OWLv2 feedback for most questions, intermediate values will be displayed with one or two extra digits rather than the entire unrounded value to make the solution easier to follow visually. However, the final answers are based on the full unrounded values stored in the system. Your answers to numeric problems are graded based on a tolerance (usually +/- 2%). Though you will not be marked incorrect for using the incorrect number of significant figures, you should always try to input the correct significant figures. Otherwise, your answer may fall outside the accepted range of answers. Answer the following questions about numerical problems in OWLv2: (a) OWLv2 uses rounded intermediate answers to calculate the final answer to a numerical problem. (b) answers are usually displayed with at least one extra digit. (c) To be marked correct, you have to enter the correct number of significant figures in your
