How many significant figures should be present in the answer of the following calculations?
a. `(0.02856xx298.15xx0.112)/0.5785`
b. `5xx5.364`
c. `0.0125+0.7864+0.0215`

Text Solution

Verified by Experts

a. The least precise term has `3` significant figures `(i.e., 0.112)`. Hence, the answer should have `3` significant figures.
b. Leaving the exact number `(5)`, the second term has `4` significant figures. Hence, the answer should have `4` significant figures.
c. In the given addition, the least number of decimal places in the term is `4`. Hence, the answer should have four significant figures.
