and making slime isnt either...
lets say it like this do you use a wrench for slime or evaporation?
nope but you do for cars

The answer is:
2.5 moles
The explanation:
when avogadro's number = 6.02 * 10^23
and when 1 mole of the sample will give → 6.02*10^23 atoms
So, ??? mole of the sample will give→ 1.52 x 10^24 atoms
∴ number of moles = (1.52 X 10^24) * 1 mole / (6.02X10^23)
= 2.5 moles
Answer:
yes it is
Explanation:
Wine, air, and gunpowder are other examples of common homogeneous mixtures. Their exact compositions can vary, making them mixtures rather than pure substances. Wine is a liquid mixture of water, ethanol, and a variety of other dissolved substances
Total number of atoms is 5.016×10²¹
Carbon and oxygen states 3.01×10²³ respectively, while hydrogen 6.02×10²³
