Respuesta :
about 8.0 moles of methane.Number of moles = MassMolar mass.
And thus we get the quotient:
128.3⋅g16.04⋅g⋅mol−1=8.0⋅moles of methane.
Note that the expression is dimensionally consistent, we wanted an answer in moles, and the quotients gives, 1mol−1=11mol=mol as required.

Answer : The moles of methane are, 8.01875 moles
Explanation : Given,
Mass of [tex]CH_4[/tex] = 128.3 g
Molar mass of [tex]CH_4[/tex] = 16 g/mole
Now we have to calculate the moles of methane.
Formula used :
[tex]\text{Moles of }CH_4=\frac{\text{Mass of }CH_4}{\text{Molar mass of }CH_4}[/tex]
Now put all the given values in this formula, we get the moles of methane.
[tex]\text{Moles of }CH_4=\frac{128.3g}{16g/mole}=8.01875moles[/tex]
Therefore, the moles of methane are, 8.01875 moles
