You would have to convert the 3 feet into inches. Since there are 12 inches in an foot you would do 3 times 12 and get 36. Then you would add the other 2 inches and get 38 inches. Next, you would do subtract 20 inches (that's how wide the chair is) from the 38 inches because you want to know how much wider the door is than the chair. Once you subtract 20 inches from 38 inches you get 18. The door is 18 inches wider than the chair.

18 inches or 1 foot and 6 inches
multiply 3 feet by 12 and add two to get the width of the door in inches then subtract 20 inches from it to get the difference

Part 1. Determine the molar mass of a 0.622-gram sample of gas having a volume of 2.4 L at 287 K and 0.850 atm. Show your work.
sdas [7]

If a sample of gas is a 0.622-gram, volume of 2.4 L at 287 K and 0.850 atm. Then the molar mass of the gas is 7.18.

<h3>What is an ideal gas equation?</h3>

The ideal gas equation is given below.

PV = nRT

The equation can be written as

\rm PV = \dfrac{m}{M} \ RT\\\\\\MPV = mRT

Where M is the molar mass, P is the pressure, V is the volume, R is the universal gas constant, T is the temperature, and m is the mass of the gas.

Then the molar mass of a 0.622-gram sample of gas has a volume of 2.4 L at 287 K and 0.850 atm.

V = 2.4 L = 0.0024

P = 0.85 atm = 86126.25 Pa

T = 287 K

m = 0.622

R = 8.314

Then we have

\begin{aligned} \rm M \times 86126.25 \times  0.0024&= 0.622 \times  8.314 \times 287\\\\\rm M &= 7.18 \end{aligned}

Then the molar mass of the gas is 7.18.

More about the ideal gas equation link is given below.
