Question

last question chemistry

Answer 1

Hi. Do you know how to start this question?

Answer 2

Just like the previous questions in this assignment, we can start by doing the calculations and then formatting our results to have the appropriate number of sig figs.

For the first one, 654.56 / 89.341 gives us 7.3265354.... and we can see from the operands that we will need our result to have 5 sig figs, since both 654.56 and 89.341 have 5 sig figs.
I will leave the rounding and the unit for this one to you

Answer 3

So this question focuses on Significant Figures in chemistry.
Simply said, significant figures are the number of figures believed to be correct.
There's several significant figure rules but we will focus on multiplication and division for now.
The product contains the same number of figures as the number containing the least sig figs used to obtain it.
