Percentage yield= actual yield/theoretical yield x100
So you would have to do-
15/22 x 100. Hope this helps!!
Answer:
I think the answer is A - they used X-ray analysis.
Explanation:
The simple formula is C = n/V
n = mols
C = Concentration or Molarity
V = Volume in Liters.
n = 2
V = 4
C = 2 / 4
C = 0.5 mol/Litre
Explanation:
In a galvanic cell, the cathode is positively charged and the anode is negatively charged.
The cathode attracts electron while the anode donates or releases electrons.
Electrons received - Cathode
Electrons donated - Anode
