1. Based on the ideal gas law, there is a simple equivalency that exists between the amount of gas and the volume it occupies. At standard temperature and pressure (STP; 273.15 K and 1 atm, respectively), one mole of gas occupies 22.4 L of volume. What mass of methanol (CH3OH) could you form if you reacted 3.39 L of a gas mixture (at STP) that contains an equal number of carbon monoxide (CO) and hydrogen gas (H2) molecules? 2. Assuming...

At standard temperature and pressure (STP; 273.15 K and 1 atm, respectively), one mole of gas occupies 22.4 L of volume. What mass of methanol (CH3OH) could you form if you reacted 4.24 L of a gas mixture (at STP) that contains an equal number of carbon monoxide (CO) and hydrogen gas (H2) molecules?

Empirical Gas Laws, Ideal Gas Law, Dalton's Law of Partial Pressures 3. A Mexible vessel is filled to a certain pressure with 12.00 L of gas. Under conditions of constant temperature and moles of gas, how does the volume of the gas change when the pressure of the gas is decreased by a factor of three? 4. A gas occupies a volume of 2.75 L at 350. mmHg and 200°C. What is the volume of the gas at 550. mmHg...
Learning Goal: To apply the ideal gas law to problems involving temperature, pressure, volume, and moles of a gas. The four properties of gases (pressure P, volume V, temperature T, and moles of gas n) are related by a single expression known as the ideal gas law: PV=nRT The variable R is known as the universal gas constant and has the value R=0.0821 L⋅atm/(mole⋅K). The units of R dictate the units for all other quantities, so when using this value...
