Answer:

60.00% is the volume percent the ethylene glycol in the antifreeze mixture.

Explanation:

Volume of the ethylene glycol in the mixture = 3.00 gal

Volume of the water in the mixture = 2.00 gal

Total volume of the mixture =3.00 gal + 2.00 gal = 5.00 gal

Volume percent the ethylene glycol :

\frac{\text{Volume of solute}}{\text{Volume of solution or mixture}}\times 100

\%=\frac{3.00 gal}{5.00 gal}\times 100=60.00\%

60.00% is the volume percent the ethylene glycol in the antifreeze mixture.

How many moles of methane are in 20.32 x 10^16 molecules
Marizza181 [45]

Taking into account the definition of avogadro's number, 3.37×10⁻⁷ moles of methane are 20.32×10¹⁶ molecules.

First of all, you have to know that Avogadro's number indicates the number of particles of a substance (usually atoms or molecules) that are in a mole.

Its value is 6.023×10²³ particles per mole and it applies to any substance.

Then you can apply the following rule of three: if 6.023×10²³ molecules are contained in 1 mole of methane, then 20.32×10¹⁶ molecules are contained in how many moles of methane?

amount of moles of methane= (20.32×10¹⁶ molecules × 1 mole)÷ 6.023×10²³ atoms

Solving:

<u><em>amount of moles of methane= 3.37×10⁻⁷ moles</em></u>

Finally, 3.37×10⁻⁷ moles of methane are 20.32×10¹⁶ molecules.
