A student collects a 125.0mL sample of hydrogen gas, but forgot to record the temperature. Later the sample is found to have a volume of 128.6mL when the temperature is 26.0oC. What was the original temperature, in Kelvin, of the gas? Show all your work and round your answer to the hundredths place.

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.

explanation:

fe 55.85 g/mol and h2o 18.02 g/mol.
