How do you express concentration in parts per billion?

Answer 1

The units parts per billion, or ppb, works just like percent, except that instead of being out of 100, it is out of 1,000,000,000 (1 x 109)

For instance, if the concentration of a certain molecule is 5 ppb, that means for every billion molecules in the mixture, only five are that one molecule.

So to convert ppb to a percent, divide by 1 x 107.

You can also use parts per million (ppm), which is out of 1 x 106, or parts per trillion, ppt, which is out of 1 x 1012.

Answer 2

Concentration in parts per billion (ppb) is expressed as the ratio of the mass of the solute to the total mass of the solution multiplied by 10^9. This is represented as:

[ \text{ppb} = \frac{\text{mass of solute}}{\text{mass of solution}} \times 10^9 ]

Answer 3

1 penny in 10 million dollars

1 second in 32 years

1 foot of a trip to the moon

1 blade of grass on a football field

1 drop of water in an Olympic-size swimming pool

Answer 4

1ppb=1ug/L and 1ug=1e-6g so you take that and divide it by the molar mass of the substance you're trying to get the molarity for. Example--> Lithium FW=6.94g/mol so (1e-6g/L)/(6.94g/mol)=1.44e-7mol/L

Answer 5

1 ppm = 1x10-6 parts per parts

1 ppb = 1x10-9 parts per parts

1 ppt = 1x10-12 parts per parts

1 ppm = 1x103 ppb = 1x106 ppt

Answer 6

You can't - one is a concentration, the other a distance.

Answer 7

1,000,000 micromoles = 1 mole
