Answer:

7.565 %.

Explanation:

  • Given the formula below:  

Error % = [True value - Measured value) /True value] ×100

  • one can Calculate the percent error for the experiment

where, True value = 42.3 g.

Measured value = 45.5 g.

Error % = [║(True value - Measured value)║ /True value] ×100

Error % = [║(42.3 g) - (45.5 g)║ /(42.3 g)] × 100 = 7.565 %.
