114.3%

True amount of solid = 1.4g

Measured amount = 3.0g

Unknown:

Percentage error = ?

Solution:

The inaccuracy in the reading is termed uncertainty.

This is the error.

Error = true value - measured value.

The values of errors are absolute.

Percentage error = $\frac{|true value - measured value|}{true value} x 100$

Percentage error = $\frac{1.4 - 3}{1.4}$ x 100 = 114.3%
