To calculate the number of atoms in 10 grams of gold, first determine the molar mass of gold, which is approximately 197 grams per mole. Using Avogadro's number, which is (6.022 \times 10^{23}) atoms per mole, you can find the number of moles in 10 grams of gold by dividing 10 grams by the molar mass (197 g/mol). Finally, multiply the number of moles by Avogadro's number to find the total number of atoms:
[ \text{Number of atoms} = \left( \frac{10 \text{ g}}{197 \text{ g/mol}} \right) \times 6.022 \times 10^{23} \text{ atoms/mol} \approx 3.05 \times 10^{22} \text{ atoms}. ]

How many atoms in 19.3 grams of gold on a sheet that is 0.00010?
To calculate the number of atoms in 19.3 grams of gold, you need to first determine the number of moles of gold. Then, you can use Avogadro's number (6.022 x 10^23) to find the number of atoms. Given that the sheet is only 0.00010 cm thick and the density of gold is 19.3 g/cm^3, you can determine the area of the sheet and then calculate the number of atoms.
One atom of gold weighs 3.27x10-22 grams-how many atoms will there be in one Kilogram of gold-Give your answer in Scientific notation correct to 2 Significant figures?
To calculate the number of gold atoms in one kilogram, we first need to determine the number of atoms in 1 gram, then multiply by 1000 to account for the kilogram. Given that one atom of gold weighs 3.27x10^-22 grams, the number of atoms in 1 gram would be 1/(3.27x10^-22) = 3.06x10^21 atoms. Therefore, in one kilogram (1000 grams) of gold, there would be 3.06x10^24 atoms.

What is the mass of potassium if a potassium sample contains 5 times the number of atoms as in 9.85 grams of gold?
The gram atomic mass of gold is 196.967 and that of potassium is 39.0983. Therefore, equal numbers of atoms of potassium are supplied by 39.0983/196.967 the mass of potassium compared with gold. 5 X 9.85 = 49.25. This contains the same number of gold atoms as 49.25(39.0983/196.967) or 9.78 grams of potassium contains of potassium atoms, to the justified number of significant digits (limited by the number "9.85", assuming that "5" is intended to be exact.)
Every drop of seawater contains approximately how many gold atoms?
