<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 = ![25^oC=[25+273]K=298K](https://tex.z-dn.net/?f=25%5EoC%3D%5B25%2B273%5DK%3D298K)
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

Answer:
Mass of water = 41.8 g
Explanation:
Given data:
Mass of water = ?
Change in temperature = 3.0 °C
Specific heat capacity = 4.184 j/g.°C
Heat absorbed = 525 j
Solution:
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
ΔT = 3.0°C
Now we will put the values in formula.
525 J = m × 4.184 j/g.°C × 3.0°C
525 J = m × 12.552 j/g
m = 525 J/ 12.552 j/g
m = 41.8 g
The answer for this one is a
