Need ! calculate the volume of each of the following gases at stp. show your work.
a. 7.6 mol ar
b. 0.44 c2h6
c. 3.6 nh3

A. V Ar = 185.7136 L

B. V C2H6 = 10.752 L

C. V NH3 = 87.97 L

Explanation:

STP:

∴ T = 25°C ≅ 298 K

∴ P = 1 atm

assuming ideal gas:

⇒ V = RTn / P

∴ R = 0.082 atm.L/K.mol

A. n Ar = 7.6 mol

⇒ V Ar = ((0.082 atm.L/K.mol)(298 K)(7.6 mol)) / (1 atm) = 185.7136 L

B. n C2H6 = 0.44 mol

⇒ V = 10.752 L

C. n NH3 = 3.6 mol

⇒ V = 87.97 L

step-by-step explanation:

whole numbers, zero or greater

answers: to make sure that all of the broken pieces of tablet were added to the water, to allow for fair comparison of all three trials, with different particle sizes to avoid experimental error
