Okay, so you need to start by finding the molar mass (grams in one mole) of nitrogen monoxide (NO).
N=14g
O=16g
So we know that NO has a molar mass of 30 grams, then just divide your given mass of 22.5 grams by the molar mass of 30 grams to find the number of molecules in your sample. The answer should be .75 molecules. Hope this helps!
Kinetic energy has increased.
The <em>Kinetic Molecular Theory</em> of gases states that the average kinetic energy of the molecules of a gas is directly proportional to its Kelvin temperature.
Thus, if the temperature of the air in a room has increased, the average kinetic energy of its molecules has increased.
Answer: The pH 0f 0.10 solution of HCl is 1.00
Explanation:
pH or pOH is the measure of acidity or alkalinity of a solution.
pH is calculated by taking negative logarithm of hydrogen ion concentration.
![pH=-\log [H^+]](https://tex.z-dn.net/?f=pH%3D-%5Clog%20%5BH%5E%2B%5D)
According to stoichiometry,
1 mole of 
gives 1 mole of 
Thus 
moles of gives =
moles of
Putting in the values:
![pH=-\log[0.10]](https://tex.z-dn.net/?f=pH%3D-%5Clog%5B0.10%5D)
Thus pH 0f 0.10 solution of HCl is 1.00
