The mole fraction of neon in the air is about .0000026. If the average molar mass of air is 28.96 g/mol, what is the concentration of neon in air in ppm?

How do you set this up?

fraction by volume = mols fraction.

2.6E-6 = fraction by volume.
2.6E-6 x 106 = ppm = 2.6 but wikipedia shows it as 18 ppm.

MOLAR MASS OF NEON=20,18 AND MOLAR MASS OF AIR=28.96 GIVEN THAT MOLE FRACTION OF NEON:AIR=2.6^-5

PPM MEANS PARTS PER MILLION

HERE WE GO.

C=((N/A)(D))(1000000)
1. N/A=20.18/28.96=0.6968232044
2.(N/A)(D)=
(6.968*10^-1)(2.6*10^-5)=1.811740331*10^-5
3.(1.811740331*10^-5)(1000000)=18.11740331 ppm to two significant figures it is equal to 18 ppm

Well, if we want to find the concentration of neon in air in parts per million (ppm), we can start by multiplying the mole fraction of neon by 1,000,000. This will convert it to parts per million. So, for your example:

Concentration of neon in air (ppm) = Mole fraction of neon × 1,000,000

Substituting the value you provided:

Concentration of neon in air (ppm) = 0.0000026 × 1,000,000

Now, let's calculate it:

Concentration of neon in air (ppm) = 2.6 ppm

So, the concentration of neon in air is approximately 2.6 ppm. Feel free to consider this answer with a pinch of clownish humor!

To find the concentration of neon in air in parts per million (ppm), you can follow these steps:

1. Convert the mole fraction of neon to a mass fraction:
Mass fraction = mole fraction x molar mass of neon
Mass fraction of neon = 0.0000026 x molar mass of neon

2. Calculate the mass of neon in air:
Mass of neon = mass fraction of neon x mass of air

3. Convert the mass of neon to ppm:
ppm = (mass of neon / mass of air) x 1000000

Let's calculate the concentration of neon in air in ppm using these steps.

To find the concentration of neon in air in parts per million (ppm), we need to use the given mole fraction of neon and the average molar mass of air.

1. Convert the mole fraction of neon to a decimal form:
Mole fraction = 0.0000026

2. Calculate the mass fraction of neon in air:
Mass fraction of neon = Mole fraction of neon * Molar mass of neon
However, we don't know the molar mass of neon, so we need to look it up. The molar mass of neon is approximately 20.18 g/mol.

Mass fraction of neon = 0.0000026 * 20.18 g/mol

3. Calculate the concentration of neon in air in ppm:
ppm = (Mass fraction of neon / Average molar mass of air) * 1,000,000

ppm = (0.0000026 * 20.18 g/mol) / 28.96 g/mol * 1,000,000

So, to set up the calculation:

ppm = (0.0000026 * 20.18) / 28.96 * 1,000,000
