Short answer: mm cf is one million cubic feet. Long answer: MM stands for 1 million. It is based on the roman numeral M (1000), so MM is 1000 X 1000, or 1,000,000. Be careful, as I have seen mcf or MCF refer to " one million cubic feet" instead of "one thousand cubic feet". A quick reality check should tell you which is meant.

The mm (usually capitalized as in "MM") stand for million. cfm stands for cubic feet per minute. So MMcfm stands for million cubic feet per minute.As a side note you may also see MMscfm which stands for "million standard cubic feet per minute," which uses the gas density at the reference temperature of exactly 60 degrees Fahrenheit. This may be different than the actual density, but it provides a way to distinguish exactly how much gas is flowing independent of temperature.
The volume is 0,046 L.
The partial pressure of hydrogen gas can be calculated by subtracting the partial pressure of helium from the total pressure. Therefore, the partial pressure of hydrogen gas would be 161 mm Hg (600 mm Hg - 439 mm Hg = 161 mm Hg).
According to Boyle's Law, if you double the volume of a gas at constant temperature, the pressure is halved. So, the pressure would decrease to 190 mm Hg when the gas sample is expanded to 800 mL.

To convert one cubic meter of natural gas to million British thermal units (mm BTU), you typically use the conversion factor that 1 cubic meter of natural gas is approximately equal to 35.3 MJ (megajoules). Since 1 mm BTU is equivalent to about 1,055 MJ, you can calculate the conversion as follows: 35.3 MJ divided by 1,055 MJ/mm BTU gives approximately 0.0334 mm BTU. Therefore, one cubic meter of natural gas is about 0.0334 mm BTU.
In mathematics an MM degree stand for a Masters of Mathematics. Lowercase mm stand for millimeters.

Are you thinking of Mm? Molar mass. Or millimeters?
Millimeter
The "mm" is the abbreviation for millimeters. So "12 mm" stands for "12 millimeters"
2 milimeters.
