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
Sis do you want my whatsapp number incase you wanna ask something. Its your wish pls dont misunderstand it or else you can give your number its your wish
