# Calculate the mass of methane that would be emitted from a piece of ground that is the size of a football pitch during a 12 week summer period.

Explain working "lack of units and inappropriate precision"
Please present an alternative version which demonstrates the use of mathematical skills

Mass of methane held within container = 0.00734kg
Internal volume of the container = 0.011 m3

0.00734
--------
0.011 = 0.667272727 ?????

When permafrost melts it relases methane gas. A typical methane emmission rate might be 250mg to (2 significant figures) of methane emitted through 1 m2 of ground surface per day, calculate the mass of methane that would be emitted from a piece of ground that is the size of a football pitch during a 12 week summer period. Express in SI units using scientific notation to an appropriate no of significant figures the area is 6500 m2 to 2 significant figures.

#### Solution Preview

Every measurement has unit and precision because we have to use a measurement device to do the measurement, different measurement devices will result in different unit and precision.

The appropriate way ...

#### Solution Summary

Unit conversions are used to calculate the mass of methane released from permafrost.
