Hey sis

Explanation:

We all know precision means the reputability of measurement and the accuracy means how close measurement is to actual value. To get the measured mass of acetone we need to subtarct the mass of the bottle from the measured mass of bottle and acetone

Mass of bottle=38.0015g

So mass of acetone in bottle 1 is 0.7783g

Mass of acetone in bottle 2 is 0.7780g

Mass of acetone in bottle 3 is 0.7786g

We can see that the measured value is near to each other. So we can say that the measurements are precise

To check accuracy, we can compare the average value of the actual mass of the acetone

Average of the acetone measurement is 0.7783+0.7780 + 0.7786/3 = 0.7783g

Percentage of difference of the average measurement to the actual mass

Actual value- measured value/ Actual value* 100

0.7791-0.7783/0.7791 *100%

=0.10℅

As difference is very small we can say its accurate

Hey sis hope my answer was very clear to you and helps
