If you have a solution that contains 46.85 g of codeine, c18h21no3, in 125.5 g of ethanol, c2h5oh, what is the mole fraction of codeine?

0.22

Explanation:

Given, Mass of = 46.85 g

Molar mass of = 299.4 g/mol

The formula for the calculation of moles is shown below:

Thus,

Given, Mass of = 125.5 g

Molar mass of = 46.07 g/mol

The formula for the calculation of moles is shown below:

Thus,

So, according to definition of mole fraction:

answer

fusion: the energy source of stars. the energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. when the core is hot enough, nuclear fusion commences. fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.
