Answer:
0.25 mol /L
Explanation:
Molarity , is the number of moles present in a liter of solution .
M = n / V
M = molarity ( unit = mol / L or M )
V = volume of solution in liter ( unit = L ),
n = moles of solute ( unit = mol ),
Moles is given mass divided by the molecular mass ,
Hence ,
n = w / m
n = moles ,
w = given mass ,
m = molecular mass .
From the question ,
The data given is as follows -
w = 25 g
m = 100 g/mol
V = 1 L
From the above data ,
Moles are given as -
n = w / m
n = 25 / 100 = 0.25 mol ,
Now , the molarity is given as ,
M = n / V
M = 0.25 mol / 1 L
M = 0.25 mol /L
It begins with carbon moving from land to the atmosphere. Through combustion, carbon turns to gaseous carbon dioxide. When the atmosphere interacts with the hydrosphere, some of the carbon dioxides dissolves in the water as dissolved carbon dioxide. This can also happen through precipitation. Some of the dissolved carbon dioxides can react with water into carbonic acid.
One way is through the burning of fossil fuels. One of the products of the burning of hydrocarbons is carbon dioxide. Another is clearing of forests. Forests are major carbon sinks since trees sequester carbon dioxide from the atmosphere.
