Mining engineers often have to deal with gases when

planning for the excavation of coal. Some of these gases,

including methane, can be captured and used as fuel to

support the mining operation. For a particular mine, 2.4 g

of CH4 is present for every 100. g of coal that is extracted.

If 45.6% of the methane can be captured and the daily pro-

duction of the mine is 580 metric tons of coal, how many

moles of methane could be obtained per day
