It is more difficult over easy. Since you haven't figured it out and came here to ask.
Answer:
The molar mass of is 96.8 g/mol
Explanation:
The given molecular formula -
Individual molar masses of each element in the compound is as follows.
Molar mass of nitrogen - 14.01 g/mol
Molar mass of of hydrogen = 1.008g/mol
Molar mass of carbon = 12.01 g/mol
Molar mass of oxygen =16.00 g/mol
Molar mass of is
Therefore,The molar mass of is 96.8 g/mol
There are 1.66 1 molecules in 1 gram of nicotine.
<u>Explanation</u>:
Nicotine is an organic compound with the chemical formula of
Given the mass of nicotine = 4.50 g
Molecular mass of Nicotine = 162.23 g/mol
Moles of a compound = given mass / molar mass of the compound
=
The Number of molecules of compound:
Moles Avogadro number = 0.0277 6.023 1
= 1.66 1 molecules.
There are 1.66 1 molecules in 1 gram of nicotine.
Answer:
B. Secondary pollutant
Explanation:
A primary pollutant is directly emitted into the atmosphere. Volcano eruptions and emissions from cars can result in primary pollutants in the air.
Secondary pollutants are not directly put in the atmosphere. They are created when two or more primary pollutants in the atmosphere react. One example is smog.
Another example is acid rain. If sulphur dioxide, nitrogen dioxide and water react, then acid rain is formed. Therefore, acid rain must be a secondary pollutant.
The best answer choice is B. secondary pollutant
