how many liters of ammonia are contained in 600mL of a solution that is 8% ammonia by volume

Sagot :

Volume of ammonia (Liters) =0.048 L

Further explanation  

The concentration of a substance can be expressed in several quantities such as moles, percent (%) weight/volume,), molarity, molality, parts per million (ppm) or mole fraction. The concentration shows the amount of solute in a unit of the amount of solvent.  

There are several concentration units in percentages that can be used:  

Percent Volume (% V / V), total volume (ml) of solute in 100 ml of solution.  

[tex]\rm \%solute=\dfrac{solute~volume}{solution~volume}\times 100\%[/tex]

Known

solution volume = 600 ml

%solute = 8%

solute (ammonia) volume =

[tex]\rm \%ammonia=\dfrac{ammonia~volume}{solution~volume}\\\\8\%=\dfrac{ammonia~volume}{600}\times 100\%\\\\ammonia~volume=\dfrac{8\%\times 600}{100\%}=\boxed{\bold{48~ml}}=\boxed{\bold{0.048~L}}[/tex]
