<u>Answer:</u> The number of moles of gas in bicycle tire is 0.210 moles
<u>Explanation:</u>
To calculate the moles of gas, we use the equation given by ideal gas which follows:
where,
P = pressure of the gas = 737 torr
V = Volume of the gas = 5.30 L
T = Temperature of the gas =
R = Gas constant =
n = number of moles of gas = ?
Putting values in above equation, we get:
Hence, the number of moles of gas in bicycle tire is 0.210 moles
Solution, colloids and suspension are different kind of mixtures.
Air and dust are not solutions, because the dust can be observed (using light).
There is a doubt about whether air and dust form a colloid or a suspension.
Colloids do not separate, while suspension's components do separate. If the dust is small enough it will remain on the air long enough to be considered a colloid for all efects.
Then, the most acceptable opinion is that the mixture of air and dust is a colloid.
So, option c. a colloid.
