Answer : The correct option is, (A)
Explanation : Given,
pH = 4.33
pH : It is the negative logarithm of hydrogen ion concentration.
First we have to calculate the pOH.
Now we have to calculate the concentration.
Therefore, the concentration is,
0.16
Explanation:
when you divided 1.2.00 with 740 you get this number.
You must first know that the number of protons and neutrons are same, and neutrons number may vary. Carbon 12 has 6 protons, 6 neutrons and 6 electrons. Sodium 23 has 12 protons , 12 electrons and and 11 neutrons. Silver 108 has 47 protons, 47 electrons and 61 electrons. Finally, Sulfur 32 has 16 protons, 16 nuetrons and 16 electrons. Basically the number of neutrons in an atom can be found by subtracting proton number from mass number
