Calculate the density of F2 gas at 27 degree Celsius and 1.00 atm pressure?
The gas law equation of PV = nRT can be re-written as P*molar mass = density*R*T
Substitute and solve for density.
Amber, Too funny i have this same question for ec College Chem at Terra! In book page 303, 35 b. Answer back of text lol!!!
since gas law equation is PV=nRT, and n=grams/mol. Then, g/v=P(M)/R(T), and density is g/v, so density=P(M)/R(T)
Why did the F2 gas go to the circus? It wanted to be a 'fluorine clown'!
Now, let's calculate the density of F2 gas at 27 degrees Celsius and 1.00 atm pressure. The molar mass of F2 is approximately 38.0 g/mol.
First, we need to convert the temperature from Celsius to Kelvin. Adding 273.15 to 27 gives us 300.15 K.
Next, we can use the ideal gas law, which states that the density (D) is equal to the molar mass (M) divided by the molar volume (V).
Using the ideal gas law equation: PV = nRT
P = pressure = 1.00 atm = 101.325 kPa
V = volume (we assume 1 mole of gas) = 22.414 L/mol
n = number of moles (again, assuming 1 mole)
R = ideal gas constant = 0.0821 L·atm/(mol·K)
T = temperature = 300.15 K
Now, let's calculate the density:
D = (Molar mass)/(Molar volume)
D = (38.0 g/mol) / (22.414 L/mol)
D ≈ 1.69 g/L
So, the density of F2 gas at 27 degrees Celsius and 1.00 atm pressure is approximately 1.69 g/L. But hey, if you ever need a density joke, just gas-k me!
To calculate the density of a gas, you need to know its molar mass and the ideal gas law.
1. Start by finding the molar mass of F2 gas (fluorine gas). Fluorine (F) has a molar mass of 19.00 g/mol, and since there are two fluorine atoms in F2 gas, the molar mass of F2 is 2 * 19.00 = 38.00 g/mol.
2. Next, use the ideal gas law, which states that PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant (0.0821 L·atm/(mol·K) at STP), and T is the temperature in Kelvin.
3. Convert the temperature from Celsius to Kelvin using the formula K = °C + 273.15. In this case, the temperature is 27 °C, so the temperature in Kelvin is 27 + 273.15 = 300.15 K.
4. Rearrange the ideal gas law to solve for the number of moles. The formula becomes n = PV / RT.
5. Substitute the given values into the formula:
- P = 1.00 atm (pressure)
- V is not given. Since it is not provided, we cannot determine the volume of the gas. Therefore, we cannot find the number of moles using the ideal gas law.
Without the volume, we cannot calculate the density of F2 gas at 27 °C and 1.00 atm pressure.
