Question

umm help i forget how to do this

Answer 1

it's stated to be an ideal gas, so you can use the formula

PV = nRT
where P is pressure, V is volume, n is moles, R is the ideal gas constant, T is temperature

some caveats:
1. you must convert temperature in C to temperature in K by adding 273.15
2. because our units are now L, moles, and K, we can use the gas constant R = 0.0821 L·atm/mol·K. remember that different units have different R values.

plug in the appropriate quantities and solve for P, pressure. based on our R value, your answer will be in atm.

Answer 2

ohh okok thank you
