Answer:

Explanation:
1. First take the cylinder volume formula:

2. Then take the values for the radius and the height of the cylinder and replace them into the formula:

3. Solve the equation:



Answer:
The molar solubility of carbon dioxide gas is
.
Explanation:
Henry's law states that the amount of gas dissolved or molar solubility of gas is directly proportional to the partial pressure of the liquid.
To calculate the molar solubility, we use the equation given by Henry's law, which is:

where,
= Henry's constant = 
= partial pressure of carbonated drink

where = p = Total pressure = 0.400 atm
= mole fraction of 

Putting values in above equation, we get:

Hence, the molar solubility of carbon dioxide gas is
.
Given,
P1 = 0.98 atm
V1 = 0.5 L
V2 = 1.0 L
P2 = ?
Solution,
According to Boyle's Law,
P1V1 = P2V2
0.98 × 0.5 = 1.0 × P2
P2 = 0.98 × 0.5 × 1.0
P2 = 0.49 atm
Answer - The new pressure is 0.49 atm.
Answer:
Since moles are just "some number of particles", and since one O2 molecule contains enough oxygen for two H2O molecules, you need 2.5 moles of O2 for 5 moles of H2O.
A. Would be the correct answer :-)
