Answer:
0.258 +- 0.0162
Explanation:
First change the uncertainty to percentage uncertainty :
%uncertainty =uncertainty /estimated value *100
0.1/51.6 * 100=0.19%
Do the same for the rest you will get:
0.1%, 1%, 5%
Then add the %uncertainties
0.19% + 0.1% + 1% +5%=6.29%
Find density:
51.6/10 * 100 * 0.20 = 0.258
Change the %percentage uncertainty to absolute uncertainty :
Absolute uncertainty = %uncertainty * the answer
6.29/100 * 0.258 = 0.0162
Answer = 0.258 +- 0.0162
After rounding:
0.26 +- 0.02
