How many parts per million of CO2 is 2.5 mole?
1.50553543e+30 ppm
Why is it dangerous to keep increasing the amount of CO2 in atmosphere?
We won't asphyxiate. But CO2 is a heat trapping gas, and it takes decades for the earth to adjust to any slight rise. Human activity has increased CO2 levels from 280 ppm prior to the industrial revolution to nearly 400 ppm today. We will pass 500 ppm before 2050, at the current rate. Many climate scientists believe 350 ppm may be the maximum sustainable level for CO2.
The concentration of carbon dioxide CO2 in air is 380 ppm What is this in a percentage using significant figures?
.000380 is 380 millionths, ppm is to millionths what % is to hundredths. If you now move the decimal two places to the right to conver to a percentage, then 380 ppm is approximately .04%, and thus, CO2 makes up .04% of the air (which is what I assume this question is refering to)
How are carbon dioxide levels affecting the atmosphere?
The amount of CO2 in the atmosphere is increasing each year. We have stations carefully tracking CO2 concentration changes. The value swings up and down seasonally, as northern hemisphere plant foliage dies in the fall and begins growing in the spring and summer. But the overall trend is upward, as humans pump more CO2 into the air each year from fossil sources than the earth can absorb. CO2 naturally rises and falls, and over the past 800,000 years the levels have varied from 250 to 290 ppm, generally swinging up or down about 5 ppm per thousand years. 7000 years ago CO2 was at 260 ppm. By only 5000 years ago it had risen to 270 and it was at 280 ppm 3000 years ago. In 1700 it was again at 280 ppm, but by 1900, in just two short centuries, it rose to 290 ppm. That was 10 times faster than the natural historic change. Still, not a huge concern. At that rate of growth we would not have exceeded 350 ppm (what many scientists consider a maximum sustainable level) for centuries to come. But we began increasing our consumption of fossil fuel, so that from 1900 to 1950 CO2 rose another 10 ppm, to 300. By 1958 it had risen to 315 ppm--15 ppm in under a decade, and it has continued accelerating in the intervening decades. We are now pushing 400 ppm, and will exceed 500 ppm before 2050.
Why are global carbon dioxide levels highest in May and lowest in October each year?
The Northern Hemisphere has much more land for vegetation to grow on compared to the Southern Hemisphere. Carbon dioxide (CO2) builds up slowly during the northern winter, when trees and plants are dormant. Then in May everything begins to grow, and CO2 is taken out of the atmosphere, so the levels start coming down. In October and November vegetation stops growing, and in its dormant state it stops absorbing CO2, so the carbon in the atmosphere increases. These levels go up and down like this every year. The readings for 1958, 1959 and 1960 show this: 1960: May: 320.5 ppm: October: 314.5 ppm 1959: May: 320.0 ppm: October: 313.5 ppm 1958: May: 318.0 ppm: October: 313.0 ppm Ppm means parts per million, so 320 ppm is the same as 0.032 percent (per hundred). The recent readings for May are: 2011: 394.35 ppm 2010: 393.22 ppm 2009: 390.18 ppm See the graph at the link below.
What is smoke density?
measures how many (usually) parts per million (ppm) of whatever smoke/gas/etc is being looked for. For instance a smoke detector looks for X ppm of smoke in air, or a CO2 sensor measures the ppm of CO2 in air - ppm is a measure of density.

How much ppm are there in co2 fire extinguisher?
It should be at least 99.5 percent CO2.
CO2 probe sensor?
A CO2 probe sensor measures gaseous carbon dioxide. It comes in two ranges, 0 to 10,000 ppm and 0 to 100,000 ppm.
How much CO2 ppm do human lungs exhale on average?
It depends on a number of factors such as age, heart rate and depth of breathing. However, on average a human being exhales around 40,000 PPM of CO2.
What ppm amount is 0.04 percent CO2?
0.04 percent is 400 per million.
What is above normal levels of carbon dioxide?
Above 400 ppm of co2 would be considered high.
What year will global warming start?
It's happening now and is a constant occurrence. Measurements of abnormally large temperature upswings were first made in the 1980s. We have broken numerous records since then. In 1950 earth's CO2 level exceeded 300 ppm for the first time in more than 800,000 years. CO2 naturally rises or falls by roughly 10 ppm over a thousand years. Between 1950 and 2014 CO2 will have risen from 300 ppm to 400 ppm, and we will exceed 500 ppm before 2050, less than 40 years from now. The temperature is expected to continue climbing for decades to come, just on the basis of present CO2 levels.

.000380 is 380 millionths, ppm is to millionths what % is to hundredths. If you now move the decimal two places to the right to conver to a percentage, then 380 ppm is approximately .04%, and thus, CO2 makes up .04% of the air (which is what I assume this question is refering to)
How many ml in 100 ppm?
In one Liter, there are 1000 milliliters. Ppm stands for parts per million. Ppm tells you the concentration of some liquid or gas in a solution. If there are 100 parts out of a million of CO2 (100 ppm), that is equal to 100/1,000,000, which means that .01% of the molecules in the mixture are CO2. mL and ppm are two different units of measurement. One represents distance and the other represents concentrations of fluids.
