You fill a balloon with 0.77 moles of gas at 36°C at a pressure of 1 atm. What is the volume of the balloon?
Answers
V = nRT/P
where:
n = number of moles of gas (0.77 moles in this case)
R = the ideal gas constant (0.08206 L·atm/(mol·K))
T = temperature in Kelvin (36°C + 273.15 = 309.15 K)
P = pressure (1 atm)
Plugging in the values, we get:
V = (0.77 mol)(0.08206 L·atm/(mol·K))(309.15 K)/(1 atm) ≈ 19.7 L
the volume of the balloon is approximately 19.7 liters.

This question is based on the concept of percentage by mass. Therefore the value of x, concentration of unknown ethanol solution is 4% when 20 gallons of a known solution is used. Option b is correct option
What is percentage by mass?
Mass percentage represents the the percentage of each element that is making a particular compound. Mass percentage does not have any unit as numerator and denominator contains the same unit.
Mathematically,
Percentage of mass = (component’s mass ÷ total mass) x 100%
According to the question the equation can be written as:
20× (x÷ 100) + 60×0.12 = 80× 0.10
x÷5 + 7.2 = 8
x÷ 5 = 0.8
x = 4%
concentration of unknown solution = 4%
Therefore, the value of x, concentration of unknown ethanol solution is 4% when 20 gallons of a solution is used. Option b is correct option

Considering the definition of molar mass and molarity, the volume of each compound is:
- NaCl= 0.1355 L
- C₂H₆O = 0.0622 L
- CH₃COOH = 0.047 L
Definition of molar mass
The molar mass of substance is a property defined as its mass per unit quantity of substance, in other words, molar mass is the amount of mass that a substance contains in one mole.
Definition of molarity
Molar concentration or molarity is a measure of the concentration of a solute in a solution and indicates the number of moles of solute that are dissolved in a given volume.
The molarity of a solution is calculated by dividing the moles of solute by the volume of the solution:
Molarity is expressed in units.
Volume required
You know that the molar mass of each compound is:
- NaCl = 58.44 g/mol
- C₂H₆O = 46.06 g/mol
- CH₃COOH = 60.0 g/mol
On the other side, you know that the mass of each compound is:
- NaCl = 2.14 g
- C₂H₆O = 4.30 g
- CH₃COOH = 0.85 g
Then, considering the definition of molar mass, the amount of moles of each compound is:
- NaCl =
= 0.0366 moles
- C₂H₆O =
= 0.0933 moles
- CH₃COOH =
= 0.0141 moles
The molarity of each compound is:
- NaCl = 0.27 M
- C₂H₆O = 1.50 M
- CH₃COOH = 0.30 M
Considering the molarity, the volume of each compound is calculated as:
- NaCl =
= 0.1355 L
- C₂H₆O =
= 0.0622 L
- CH₃COOH =
= 0.047 L

molar mass:
molarity:
number of moles : 2.14 / 58.44 = 0.0366 moles
V = n / M => 0.0366 / 0.270 = 0.1355 L
__________________________________________
b) C2H6O = 46.06 g/mol
number of moles : 4.30 / 46.06 = 0.0933 moles
V = n / M => 0.0933 / 1.50 = 0.0622 L
___________________________________________
c) CH3COOH = 60.0 g/mol
number of moles : 0.85 / 60.0= 0.0141 moles
V = n / M => 0.0141 / 0.30 = 0.047 L
