Explain how you would determine the molar mass of c2h6.

Molar mass of ethane is determined by adding atomic mass of all the constituent atoms.

Explanation:

Molar mass of a molecule is determined by adding all the atomic masses of constituent atoms.

In ethane molecule, there are two carbon atoms and six hydrogen atoms.

Atomic mass of carbon is 12g and atomic mass of hydrogen is 1g.

So molar mass of ethane is- or or 30g.

the mantle

explanation:

earth is divided into three layers: the crust or the outermost layer on which we live; the underlying, middle layer - the mantle - and the core (the innermost layer of earth).

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation
