A sample of propane is found to have a volume of 491cm^3 at 17^circ C and 725 mmHg. Calculate the volume under STP (standard temperature and pressure) (You answer should be to the hundreths or 2 decimal places: 0.00) Type your answer...

To calculate the volume of propane under standard temperature and pressure (STP), we use the **combined gas law**: Where:- are the initial pressure, volume, and temperature.- are the final pressure, volume, and temperature at STP.### Step 1: Write down the given values- Initial volume ( ) = - Initial temperature ( ) = - Initial pressure ( ) = At STP:- Standard temperature ( ) = - Standard pressure ( ) = We need to find the final volume ( ).---### Step 2: Rearrange the combined gas law to solve for ---### Step 3: Substitute the known values ---### Step 4: Perform the calculations step by step1. Multiply the numerator: 2. Multiply the denominator: 3. Divide the results: ---### Final Answer:The volume of propane under STP is:
