Question

Perform the following calculation, giving the answer in the correct number of significant digits. (1.145 x 109 g/mol) (0.0035 mol)/(8.57 x 10 g/mL)=

Answer 1

The answer is 0.005097 mL.

Step-by-step explanation:

Significant figures : The figures in a number which express the value of the magnitude of a quantity to a specific degree of an accuracy is known as significant digits.

Given :

`x=((1.145 x 109 g/mol)* (0.0035 mol))/((8.57 x 10 g/mL))`

`x=(0.4368 g)/(8.57* 10 g/mL)=0.005097053 mL`

`x=0.005097053 mL\approx 0.005097 mL`
