by making sure they are in the lowest ratio. by adding them to see if they total 100. by checking that they are whole-number multiples. by dividing them by the molar mass.
Answer: The molar mass of the gas is 9.878 g/mol.
Explanation:
According to Graham's law, the rate of diffusion is inversely proportional to square root of molar mass of gas.
where,
M = molar mass of gas
As given gas diffuses 1/7 times faster than hydrogen gas. So, its molar mass is calculated as follows.
where,
= molar mass of hydrogen gas
= molar mass of another given gas
= rate of diffusion of hydrogen
= rate of diffusion of another given gas = 
Substitute the values into above formula as follows.
Thus, we can conclude that the molar mass of the gas is 9.878 g/mol.
Answer:

Explanation:
Here we add lone paris,to the structure of caffeine.
<h3>What is caffeine?</h3>
Caffeine is a type of drug. It is used as a cognitive inhancer.
We've been looking at then following structure. We definitely would like to look at it is the geometries of some of the centers. We'll look to it geometry here. Yes, yeah. Down here as well. We have a bonding angle of less than 107.5 because we have a trig onal planer with a bonding angle of 120. This is the site has a geometry with all the bounding angles of 109.5. it is the funding angles of less than 107.5 carbon site here and less than 120 carbon site of here are the tribunal to the parameters. My substitute if luck with the has the same geometry with bonding angles as before.
