How many moles of CO\(_2\) are produced when ethanol is burnt with 6g of oxygen

C2H5OH + 3O2 —> 2CO2 + 3H2O
from the equation, we have 3moles of O2 : 2moles of CO2

NOTE: Since u r comparing in moles and grams of O2 is give as 6g, we can look for its particular mole i.e n = m/M = 6/32 = 0.1875mol

Therefore, 3moles of O2 —— 2moles of CO2
Then, 0.1875mol of O2 —— x
Cross multiply
X = (0.1875 x 2)/3 = 0.125mol

Hope it helps 😊
