How many moles are there in 1.50 g of ethanol,CH₃CH₂OH? A) 0.0145 mol B) 0.0326 mol C) 30.7 mol D) 69.0 mol

Question

Quizplus · Accepted Answer

To find moles of ethanol, we first need to determine its molar mass.

Molar mass of ethanol = 2(12.01 g/mol) + 6(1.01 g/mol) + 1(16.00 g/mol) 
= 46.07 g/mol

Now we can calculate number of moles:

moles = mass/molar mass = 1.50 g/46.07 g/mol ≈ 0.0326 mol

Therefore, the answer is B.
