How many moles of a gas at 100°c does it take to fill a 0.50 l flask to a pressure of 1.25 atm?

0.020 moles
0.053 moles
0.086 moles
0.204 moles

The answer to your question is:  0.02 moles

Explanation:

Data

n = ?

T = 100°C = 373 °K

V = 0.5 l

P = 1.25 atm

R = 0.082 atm L/mol °K

Formula

                    PV = nRT

Substitution

                  n = PV / RT

                  n = (1.25)(0.5) / (0.082)(373)

                  n = 0.625 / 30.59

                  n = 0.02 moles

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.

answer: i have one answer

acids are substances that ionize (break off) in an aqueous solution to produce hydrogen (h+) ions

explanation:

hope this and sorry i could only come up with one answer!
