1.2
Measurements using tool B are as follows: 1.5, 1.6, 1.4, 1.5, 1.4, 1.6 = Average value of
1.5
What is the %ERROR of Tool A?
O a. 2.2%
Ob..20%
O C. 20%
O d. 22%
Check Answer

Answer 1

20%

Step-by-step explanation:

Given that:

Actual weight of 1 mL of water =. 1g

Average weight using :

TOOL A = 1.2

TOOL B = 1.5

Percentage Error of TOOL A:

(|approximate measurement - actual measurement| / actual measurement) * 100%

(|1.2 - 1| / 1) * 100%

(0.2 / 1) * 100%

0.2 * 100%

= 20%
