1. How many molecules of S2 gas are in 756.2 L? a. 2.032 x 1025 molecules S,

b. 3.022 x 1023 molecules S,

c. 4.302 x 10 molecules S

d. 8.203 x 10' molecules S2

There are molecules gas are in 756.2 L.

Explanation:

It is known that 1 mole of any gas equals 22.4 L at STP. Hence, number of  moles present in 756.2 L are calculated as follows.

According to mole concept, 1 mole of every substance contains molecules.

Therefore, molecules of S present in 33.76 moles are calculated as follows.

Thus, we can conclude that there are molecules gas are in 756.2 L.

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.

i just learnt this recently but i need to look through my notes again
