2. a volume is measured experimentally as 4.26 ml. what is the percentage error, given that
the correct value is 4.15 ml?
measurements and calculation

0.73% error

Explanation:

Take the absolute value of the measured value minus the actual value and divive it by the actual value. Then multiply it by 100%.

I 4.26-4.15 I = 0.11/4.15 = 0.007333 x100% = 0.73%

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.
