What is the molar mass of 2-propanol (c3h8o)?

60 g C3H8O

Explanation: Solution:

Carbon C = 12 x 3

Hydrogen H = 1 x 8

Oxygen O = 16 x 1

Molar mass = 60 g C3H8O

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.

your answer is a. the enthalpy of formation for a pure element in its standard state is always positive.
