Question

the mass of oil is sought to be measured by putting it in a vessel the weighing machine read 990.54 gram the mass of the empty vessel was found to be 10. 32 gram the weighing scale has a least count of 0.01 g find the absolute error in the measurement of oil.

Answer 1

Explanation:

Mass of oil = (reading of weighing machine) – (mass of empty vessel)

Mass of oil = 990.54 g – 10.32 g

= 980.22 g

Since least count is 0.01 g, the mass of oil can be plus or minus 0.01 g i.e. 980.23 g or 980.21 g.

Hence absolute error is +0.01 g or – 0.01 g.
