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.

The Digit term for moles of gas?

Exponential value (consider "sign") for moles of gas?

What are the units for moles of gas?
