A10-ml graduate weighs 42.745 g. when 5 ml of distilled water are measured in it, the combined weight of graduate and water is 47.675 g. by definition, 5 ml of water should weigh 5 g. calculate the weight of the measured water and express any deviation from 5 g as a percentage of error.

The measured weight of the water = 4.93 g

The percentage error in measured value = 1.4%

Step-by-step explanation:

Given:

Weight of the 10-mL graduate = 42.745 g

Combined weight of graduate and 5 mL water = 47.675 g

5 mL of water should weight = 5 g

thus, actual value of 5 mL water = 5 g

Now,

The measured weight of the water

= (Combined weight of graduate + 5 mL water) - Weight of the 10-mL graduate

= 47.675 g - 42.745 g

= 4.93 g

The percentage error in measured value

=

=

or

= 1.4%
