Nitric oxide is a colorless gas with the formula NO. It is one of the principal oxides of nitrogen. Nitric oxide is a free radical, i.e., it has an unpaired electron, which is sometimes denoted by a dot in its chemical formula
Answer:
The partial pressure of bar.
Explanation:
Given:
Volume L
Total pressure bar
Temperature of system K
Moles of nitrogen mole
Partial pressure bar
From ideal gas equation,
Where = gas constant
First finding partial pressure of nitrogen
bar
We know, total pressure is given by
bar
Therefore, the partial pressure of bar.
<u>Given:</u>
# Molecules of NaOH = 1.50 * 10²³
<u>To determine:</u>
The # moles of NaOH present in the given molecules
<u>Explanation:</u>
By definition:
1 mole of NaOH corresponds to Avogadro's number i.e. 6.023*10²³ molecules
Therefore the moles of NaOH corresponding to the given molecules would be = 1.50*10²³ molecules NaOH * 1 mole NaOH/6.023*10²³ molecules NaOH
= 0.249 moles
Ans: 0.249 moles of NaOH
The conversion of pressure from kilopascal to atmosphere can be done by the dimensional analysis using the proper conversion factor. Shown below is the calculation,
(2.000 x 10^4 kPa)( 1 atm / 101.324 kPa) = 197.38 atm
Thus, the pressure in atmosphere is 197.38 atm.
