Moles of methane. No half molecules, I think!
2.50 moles methane (1 mole C/1 mole CH4)(6.022 X 1023/1 mole C)
= 1.51 X 1024 molecules of carbon
--------------------------------------------
The density of methane at 250 bar pressure would be approximately 191 kg/m^3.
One RBC contains about 250 million Hemoglobin molecules
It's a mixture of hydrogen, carbon and other 'trace' elements. Natural gas is a naturally occurring hydrocarbon gas mixture consisting primarily of methane, but commonly including varying amounts of other higher alkanes, and sometimes a small percentage of carbon dioxide, nitrogen, hydrogen sulfide, or helium. All is removed from the methane before it is used. We have from 250-100 years of natural gas left depending of the amount of usage.
250 of them.

There are 19 13s in 250. 250/13 =19.23
250 kilograms = 250 000 grams
250 meters is the same as 250 meters.
To find out how many 5's are in 250, you divide 250 by 5. When you perform the division, 250 ÷ 5 equals 50. Therefore, there are 50 fives in 250.
250 250
To find out how many times 10 goes into 250, you divide 250 by 10. The calculation is 250 ÷ 10 = 25. Therefore, 10 goes into 250 a total of 25 times.
