How many grams of AgNo3 are required to make 25 ml of .80M solution
Aleks [24]

Answer:

<u>3.39 grams </u>of AgNo3 are required to make 25 ml of .80M solution

Explanation:

Molarity , M = 0.80

Volume = 25 ml

=\frac{25}{1000} L

V = 0.025 L

molarity = \frac{moles}{Volume\ of\ solution(L)}

M=\frac{n}{V}

Here n = number of moles

n=M\times V

n=0.8\times 0.025

n = 0.02 mole

moles = \frac{given\ mass}{Molar\ mass}

Molar mass of AgNO3 = 169.87 g/mol

mass =\frac{n}{Molar\ mass}

mass=\frac{0.02}{169.87}

Mass = 3.397 g

CO is a primary pollutant.
Anuta_ua [19.1K]

True

Carbon monoxide is a primary pollutant which no odor results from incomplete combustion of fuel. The man sources are gasoline and burning of biomass.

Depending on the source of emission, pollutants can be classified into two groups that is primary and secondary pollutants.

A primary pollutant is emitted in the atmosphere directly from a source. It can be either natural sch as volcanic eruptions, sandstorms or man-made that is due to industrial and vehicle emissions.  Examples of primary pollutants are nitrogen oxides, carbon monoxide and particulate matter.

Secondary pollutant is due to interactions between primary and secondary pollutants. These can be chemical or physical interactions. Examples are photo-chemical oxidants and secondary particulate matter.

Therefore, carbon monoxide CO is a primary pollutant.
