calculate the number of moles in 32g of methane.
Molar mass of methane CH4 is =16 grams
Number of moles is calculated as given mass /molar mass
Given mass = 32g and Molar mass =16 gram
∴ no. of moles of methane in 32 gram sample = 32/16 = 2 moles.
Calculate hte number of moles of : (a) CO2 which contain 8.00 g of O2 (b)methane in 0.80 g of methane.
