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.
