What is the concentration in #"ppm"# if #18.5g# of solute are dissolved in a #125L# volume?

Answer 1

Henry Antrim

Well #1*"ppm"# #=# #1*mg*L^-1#.......

And so we set up the quotient, #"milligrams of solute"/"litres of water"#

#=(18.5*gxx10^3*mg*g^-1)/(125000*gxx10^-3*L*g^-1)=148.0*"ppm"#

The concentration in parts per million (ppm) is calculated as follows:

Concentration (ppm) = (mass of solute / volume of solution) * 10^6

Substituting the given values:

Concentration (ppm) = (18.5 g / 125 L) * 10^6 = 148,000 ppm

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
