Step-by-step explanation:
To solve this, we can use the ideal gas law, which is PV = nRT.
In this equation:
- P is the pressure we want to find.
- V is the volume, which is 4.8 L.
- n is the number of moles, which is 0.49 moles.
- R is the ideal gas constant. Since we want the pressure in atmospheres, we'll use the value of R that has atmospheres in its units, which is 0.0821 L·atm/(K·mol).
- T is the temperature in Kelvin. We need to convert the given temperature from Celsius to Kelvin by adding 273.15 to it. So, 25 degrees Celsius is 298.15 K.
Substituting these values into the equation, we get:
P = nRT / V
P = (0.49 mol)(0.0821 L·atm/K·mol)(298.15 K) / 4.8 L
Now, just do the math to find the pressure. hehe
