Answer:

9.2-g of ethanol

Explanation:

The question is asking for us to solve for the mass of ethanol given the moles of it.

We can do this by going from mol -> grams using the <u>molar mass of ethanol</u> (46.068g).

Start off with the moles given (0.20mol) and multiply it by the molar mass of ethanol (46.068g).

This would give the mass of 9.214-g, but since our question has only 2 significant figures, round off your final answer to the same number of sig. figs.

So your final answer would be 9.2-g of ethanol.

***Molar mass is calculated by adding the masses of each element (found in periodic table) by how many times they are in the molecules.

Change 23 degrees Celsius to F
Fed [463]
Rewrite the formula C=5/9(F-32) substituting 23 for C: 23=5/9(F-32), then multiply both sides by the reciprocal of 5/9.
(9/5)*(23)=(9/5)*5/9(F-32)
41.4=F-32; add 32 to both sides.
41.4+32=F-32+32
73.4=F
