A single atom of carbon contains 6 protons and 6 neutrons in its nucleus, surrounded by 6 electrons. Therefore, there are 6 atoms in a carbon molecule.
6.55 * 1024 atoms = ? moles of carbonTake the number of atoms and divide it by Avogrodos constant (6.02 * 1023). Note that if you are looking to have your units cancel, multiply the number of atoms times 1 mole and divided by atomic mass. But if you know why it is just multiplied by one, there is no reason to put it in the formula.6.55 * 1024 atoms / (6.02 * 1023) = 10.9 molescarbon
To find the number of moles of CaCl2, first calculate the molar mass of CaCl2: Ca: 40.08 g/mol Cl: 35.45 g/mol (x2 since there are two Cl atoms) Total molar mass: 40.08 + 35.45(2) = 110.98 g/mol Next, calculate the number of moles: 2.41 x 10^24 formula units / Avogadro's number (6.022 x 10^23) = 4 moles of CaCl2.
To convert atoms to moles, you divide the number of atoms by Avogadro's number (6.022 x 10^23). So, 2.80 x 10^24 atoms of silicon would be 4.65 moles.
To find the number of moles, you need to divide the given number of atoms by Avogadro's number, which is approximately 6.022 x 10^23 atoms/mol. So, ( \frac{4.2 \times 10^{24}}{6.022 \times 10^{23}} \approx 7 , \text{moles of Pb atoms})
1.08 x 10^25
1,400,000,000,000,000,000,000,000
2.44 times 10 to the 24th power
0.00000000000000000000000167
5,970,000,000,000,000,000,000,000 kilograms.
Ten to the 24th power, 1024, is called ten to the 24th power.
2.44 x 1024 = 2440000000000000000000000
2 to the 24th power is 16,777,216.
To find the number of moles, divide the number of molecules by Avogadro's number, which is (6.022 \times 10^{23}) molecules/mol. (3.75 \times 10^{24}) molecules of carbon dioxide is equivalent to 3.75 moles of carbon dioxide.
5.974 x 10^24 (5.974 times 10 to the 24th power)
1.292557881
The answer is 6,227 moles.
