We know that, 1 mole of any substance contain 6.022 X 10^23 atoms/molecules.

Thus,  6.022 X 10^23 atoms = 1 mole
Therefore, 1.29x10^24 = \frac{1.29X10^2^4}{6.022X10^2^3}
                                     = 2.14

Thus, 2.14 moles<span> are present in 1.29x10^24 hydrogen atoms in HF.</span>

Explanation:

According to Avogadro's number there are 6.023 \times 10^{23} atoms present in one mole.

Therefore, we will calculate the number of moles present in 1.29 \times 10^{24} atoms as follows.

                 Number of moles = \frac{1.29 \times 10^{24}atoms}{6.023 \times 10^{23}}atoms/mol

                                             = 2.14 mol

Therefore, we can conclude that there are 2.14 moles present in 1.29 \times 10^{24} hydrogen atoms in HF.

What is the volume of the granite piece in cubic centimeters
Ghella [55]
Hi there!

Your correct answer will be 12.2 cm³.

This is how you get there:

1 mL = 1 cm³

With this one conversion factor, you can extrapolate the final answer. When you add the granite to the water, which is filled to 25.0 mL, the water level then moves to 37.2 mL. If you subtract the before volume from the volume after, you will get an answer of 12.2 mL. Then use the conversion factor and, voila! 12.2 cm³

I hope this helps!
