How many moles are 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 the number of moles of ethanol, we need to use the formula:

moles = mass / molar mass

The molar mass of ethanol (CH3CH2OH) is:

12.01 + 3(1.008) + 2(12.01) + 1.008 + 16.00 = 46.07 g/mol

So the number of moles of ethanol is:

moles = 1.50 g / 46.07 g/mol = 0.0326 mol

Therefore, the best choice is B) 0.0326 mol.
