Jill and Susan violated safety procedures by not properly listening and/or reading over the instructions to know all the materials, steps, and equipment they need for the lab. Hope this helps!
No the sun is the biggest star in the universe.
Answer:
0.64 mol
Explanation:
Using ideal gas equation as follows;
PV = nRT
Where;
P = pressure (atm)
V = volume (L)
n = number of moles (mol)
R = gas law constant (0.0821 Latm/molK)
T = temperature (K)
According to the information provided in this question;
P = 0.72atm
V = 22 L
T = 30°C = 30 + 273 = 303K
n = ?
Using PV = nRT
n = PV/RT
n = (0.72 × 22) ÷ (0.0821 × 303)
n = 15.84 ÷ 24.88
n = 0.64 mol
The answer is B, distillation.
