A gas was collected in a 10.0 L cylinder under a pressure of 730 mmHg while at 30.0oC. Determine each of the following:
Convert pressure into atm. Consider same number of SF as given. Do NOT include units, just numerical value.
Convert temperature into K. Consider same number of SF as given. Do NOT include units, just numerical value.
Take a moment and solve through for moles of gas (n = ?). Take SF into consideration, final answer in SN.

To convert the pressure from mmHg to atm, divide the pressure value by 760 mmHg, which is equivalent to 1 atm. In this case, you would divide 730 mmHg by 760 mmHg to get the pressure in atm.
To convert the temperature from degrees Celsius to Kelvin, add 273.15 to the Celsius temperature. In this case, you would add 273.15 to 30.0oC to get the temperature in Kelvin.
To solve for the number of moles of gas (n), you can use the ideal gas law equation: PV = nRT. Rearrange the equation to solve for n: n = PV / RT. Substitute the given values into the equation: n = (pressure in atm * volume in liters) / (gas constant * temperature in Kelvin).
The digit term for moles of gas would be the numerical value you obtain when you solve for n.
The exponential value for moles of gas would depend on the significant figures in the given values and the final answer. Ensure that the answer is rounded to the appropriate number of significant figures according to the rules of significant figures.
The units for moles of gas would be mol, which stands for moles.
