# How ppm is used in cars?

In measuring exhaust emissions.

### How many ml in 1 ppm?

You can't compare the two directly. A "mL" is a milliliter, and is a measure of volume (it is one thousandth of a liter). A "ppm" is a part-per-million, and is a concentration. A ppm is used in exactly the same way as a percent (%) is used. A percent is really part-per-hundred. A ppm is a much lower concentration, but is used in the same way. Without knowing more information about the problem, there…

### How do you covert from 5 ppm to percent?

ppm means 1/1,000,000; percent means 1/100. Therefore, every percent is equal to 10,000 ppm. To convert from ppm to percent, you divide by 10,000. ppm means 1/1,000,000; percent means 1/100. Therefore, every percent is equal to 10,000 ppm. To convert from ppm to percent, you divide by 10,000. ppm means 1/1,000,000; percent means 1/100. Therefore, every percent is equal to 10,000 ppm. To convert from ppm to percent, you divide by 10,000. ppm means 1/1,000,000…

### Why are carbon dioxide levels decreasing?

Carbon dioxide levels are not decreasing in the atmosphere, in fact, they are increasing. In 1960 levels were 316 ppm. In 1970 levels were 325 ppm. In 1980 levels were 338 ppm. In 1990 levels were 353 ppm. In 2000 levels were 369 ppm. In 2010 levels were 388 ppm. Jan of 2012 levels were 393.09 ppm. As of today we are at 393.68 ppm at Manua Loa.

### How do you prepare solution of 1ppm from 1000 ppm solution?

Assuming that 100 ml of 1 ppm solution has to be produced, Volume required from 1000 ppm solution = 1 ppm x 100 ml / 1000 ppm = 0.1 ml thus, 0.1 ml volume should be measured from 1000 ppm solution and transferred into a 100 ml volumetric flask. Then the solvent used in preparing the solution should be added upto the mark of the volumetric flask to prepare 1 ppm solution. The equation C1…

### What is ppm in chemistry?

Parts per million (ppm) is a measure of concentration that is used where low levels of concentration are significant. The ppm value is equivalent to the absolute fractional amount multiplied by one million (106). It is a term with several variants in meaning, so the meaning should be made clear if this term is used. Parts per million is related to percent (parts per hundred) as follows:1% = 10,000 ppm or 1/100 = 10,000/1,000,000.

### By how much percent has carbon dioxide in the air increased since 1860?

In 1860 the percentage of carbon dioxide in the air was 278 ppm (parts per million), which is 0.0278%. This had been the average figure for the previous 2000 years of the pre-Industrial Age. In 1900 it was 295 ppm. In 1960 it was 315 ppm. In 1980 it was 335 ppm. In 1990 it was 350 ppm. In 2000 it was 369 ppm. In 2010 it was 388 ppm. In 2011 it was 392…

### How do you calculate the fertilizer requirement from percentage to ppm and ppm to percentage?

There is a factor of 10,000 between ppm and percentage: ppm stands for parts per million, whereas percent means per hundred, and there is a factor of 10,000 between one hundred and one million. To go from ppm to percentage, divide my 10,000 and from percentage to ppm multiply by 10,000. Hope this helps.

### What makes up Jupiters atmosphere?

Jupiter's atmosphere is composed of the following: Molecular hydrogen (H2) - 89.8% (+/- 2.0%) Helium (He) - 10.2% (+/- 2.0%) Methane (CH4) - 3000 ppm (+/- 1000 ppm) Ammonia (NH3) - 260 ppm (+/- 40 ppm) Hydrogen Deuteride (HD) - 28 ppm (+/-10 ppm) Ethane (C2H6) - 5.8 ppm (+/- 1.5ppm) Water (H2O) - 4 ppm (varies with pressure) Small amounts of aerosols, including ammonia ice, water ice, and ammonia hydrosulfide
