sorry what us this i don't get it
The atoms of a substance can be determined by dividing the given mass of the substance by the molar mass. This results to moles of the substance. Then we multiply by the Avogadro's number. In this case, we divide 1 g by 58. 69 g/ mol and multiply by 6.022 x10^23 atoms / mole. The answer is 1.03 x10^22 atoms

Explanation:
Ammonia is a typical weak base. Ammonia itself obviously doesn't contain hydroxide ions, but it reacts with water to produce ammonium ions and hydroxide ions. My findings said that ammonia is a weak base, potassium hydroxide is a strong base, vinegar is a weak acid and ethyl alcohol is a weak acid.
Vinegar and ethyl alcohol are eliminated as they are acids. The question is on bases.... Potassium hydroxide is a strong base. So we are left with ammonia, being a weak base.
A is your answer
Answer:
(a) The diode voltage,
0.776 V
(b) The diode current,
3.81 x 10⁻²⁰ A
Explanation:
Given;
saturation current in diode,
= 10⁻¹⁷ A
nonideality factor, n = 1.05
(a) the diode voltage
Given diode current,
= 70 μA = 7 x 10⁻⁶ A
Diode voltage is calculated as;

Where;
is thermal voltage at 25°C = 0.025

b) the diode current for VD = 0.1 mV
