How many moles are there in 8.25 x 1026 molecules of methane?

1370moles

Explanation:

Given parameters:

Number of molecules in methane  =  8.25 x 10²⁶molecules

Unknown:

Number of moles of methane  = ?

Solution:

A mole of any substance contains the Avogadro's number of particles which is 6.02 x 10²³molecules;

            6.02 x 10²³ molecules is contained in 1 mole of a substance

            8.25 x 10²⁶molecules  of methane will contain   = 1370moles

why is arctic sea ice important? arctic sea ice keeps the polar regions cool and moderate global climate. sea ice has a bright surface; 80 percent of the sunlight that strikes it is reflected back into space. as sea ice melts in the summer, it exposes the dark ocean surface.
