7.565 %.
Explanation:
Given the formula below:Error % = [True value - Measured value) /True value] ×100
one can Calculate the percent error for the experimentwhere, 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 %.
