Answer: 25g/ml
Explanation:
Density = 100.0g/ 4.0mL = 25g/mL
Separation by density would be the best method to separate oil and vinegar.
Explanation:
The given data is as follows.
P = 1.13 atm, V = 43.8 L
T = = (22.4 + 273) K = 295.4 K
Now, using the ideal gas equation we will find the number of moles as follows.
PV = nRT
n =
n = 2.042 mol
Thus, we can conclude that 2.042 mol of must decompose.
The correct answer is C. I hope this helped!! :D
the second statement is the correct one quarks are needed to balance charges in all subatomic particles such as neutrons, protons and electrons
