Question
On a sheet of paper, write the word or phrase that completes each sentence. In the ideal gas law, R is a fixed value called the In the ideal gas law, n stands for the number of If you are given the mass of a gas sample, you must convert this to before using the ideal gas law. On a sheet of paper, write the letter of the answer to each question. What is the volume of 82.0 g of NH_3 gas at STP? 0.215 L 17.0 g 62.2 L 108 L What mass of krypton gas has a volume of 2.33 L at 53^degree C and 311 kpa? 22.4 g 44.8 g 342 g 2,080 g 17.0 g of Cl_2 gas has a volume of 9.22 L at 17^degree C. What is its pressure? 0.618 atm 1.24 atm 43.8 atm 62.6 atm On a sheet of paper, write the answer to each question. Show all calculations. Solve the equation PV = nRT for R. What is the unit of R if P is in atmospheres, V is in liters, n is in moles, and T is in kelvins? 25.7 L of O_2 gas is at 35^degree C and 121 kp_a. What is its mass? 83.2 g of N_2 O gas is at 73^degree C and 0.352 atm what is its volume? 75.2 g SO_3 gas has a volume of 42.1 L and a pressure of 69.6 kp_3. What is its temperature in kelvins?Explanation / Answer
answer 1
R, known as the the gas constant,
answer 2
number of mole of gas (n)
answer 3
moles
answer 4
option D is correct
answer 5
option A is correct
answer 6
option B is correct
answer 7
atm L / moles-k
answer 8
n = PV /RT = 1.21 MOLES
mass = moles * molar mass o2 = 19.43 g
