Sig fig question?
2.79 kg = 2790 g

536 mg= .536 g



Add together

2790 + .536 + 21.71 = 2812.246g



Now do Sig Figs

Since the lowest amount of sig figs in the question was 3, the answer also has to be 3 sig figs

This can be written as follows: 2.81 * 10^3



Glad to help

=2812.25g

=2.8*10^3

In this case, you need to find the lowest decimal place, but you need to convert kg and mg to the standard unit, g first.
