How do I solve this problem - i37_tinypic_com/qqeo8w.jpg (replace the underscore with a dot)
It gives the pressure, volume, and temperature and the only formula that has all those values is PV=nRT but I don't know where to get the number of moles since it doesn't give any element.
I tried pasting that in, after making the changes, and didn't get anything. Perhaps you can type in the problem in words.
Hello, I finally got it after like an hour and a half of trying.
Basically, it gave the pressure, volume, and temperature and was asking what the new pressure is after reducing the volume and increasing the temperature.
So happy I finally got it. :)
Good work. You ALWAYS feel good after figuring out those tough ones on your own.
To solve the problem, you need to find the number of moles (n) in the ideal gas equation, PV = nRT. The given information includes pressure (P), volume (V), and temperature (T), but it does not directly provide the number of moles. However, we can still determine the number of moles using the ideal gas law if we have additional information.
Here's how you can solve the problem step-by-step:
Step 1: Convert the given pressure, volume, and temperature values to the correct units. Make sure the pressure is in units of Pascal (Pa), volume in cubic meters (m³), and temperature in Kelvin (K).
Step 2: Use the ideal gas equation, PV = nRT, and rearrange it to solve for the number of moles (n):
n = PV / (RT)
Step 3: Substitute the given values (P, V, and T) into the equation.
n = (P * V) / (R * T)
Step 4: The ideal gas constant (R) is a constant value that depends on the units used in the ideal gas equation. The commonly used value for R is 8.314 J/(mol·K).
Step 5: Plug the values of P, V, R, and T into the equation and calculate the number of moles (n).
n = (P * V) / (R * T)
By following these steps, you should be able to find the number of moles (n) required to solve the problem.
