**Answer: True.**

**Explanation: A teakettle does have a greater frequency than a drumbeat. The teakettle has a higher pitched sound and frequency than a low pitched sound like a drumbeat. So a teakettle is high and a drumbeat is low.**

There a 9 planets in the solar system.

First, you need to find how much moles does 6.59*10^24 atoms of Carbon represents.

The Avogadro number represents one mole of a substance. The Avogadro number is about Na=6.02*10^23.

So, to find the mole number, you divide the number of atoms you have by the Avogadro number: n=N/Na (n=number of mole, N=number of atoms, Na=Avogadro Number).

So n=6.59*10^24/6.02*10^23 = 10.94 moles.

So to find the mass in grams of a certain number of moles, you multiply the mole number by the Molar mass of the substance you're studying.

m=n*M (m=mass in grams, n=number of moles, M=Molar mass)

The molar mass of the carbon is 12.01 g/mol.

So m=10.94 * 12.01 = 131.38 grams.

So There's 131.38 grams in 6.59*10^24 atoms of Carbon.

Hope this Helps! :)
