What is the mass of one gold atom in kilograms?

Short Answer

Expert verified
Answer: The mass of one gold atom is approximately 3.27 x 10^{-25} kg.

Step by step solution

01

Identify the atomic weight of gold

The atomic weight of gold (Au) is approximately 197 atomic mass units (amu), which can be found on the periodic table.
02

Convert atomic weight to grams

One atomic mass unit is approximately 1.66053906660 x 10^{-27} kg (according to the international unit system). To convert the atomic weight of gold (197 amu) to kilograms, multiply the atomic weight by the conversion factor: Gold_mass_kg = 197 amu * 1.66053906660 x 10^{-27} kg/amu
03

Calculate the mass of one gold atom

Now, we'll use Avogadro's number to find the mass of one gold atom in kilograms. Avogadro's number is approximately 6.02214179 x 10^{23} particles (atoms) per mole. Gold_mass_kg_per_atom = Gold_mass_kg / Avogadro's_number Gold_mass_kg_per_atom = (197 amu x 1.66053906660 x 10^{-27} kg/amu) / (6.02214179 x 10^{23} atoms/mole)
04

Calculate the final answer

Finally, we can plug in the values and calculate the mass of one gold atom in kilograms: Gold_mass_kg_per_atom 鈮� (197 x 1.66053906660 x 10^{-27}) / (6.02214179 x 10^{23}) Gold_mass_kg_per_atom 鈮� 3.27076511 x 10^{-25} kg So the mass of one gold atom is approximately 3.27 x 10^{-25} kg.

A diver rises quickly to the surface from a 5.0 -m depth. If she did not exhale the gas from her lungs before rising, by what factor would her lungs expand? Assume the temperature to be constant and the pressure in the lungs to match the pressure outside the diver's body. The density of seawater is $1.03 \times 10^{3} \mathrm{kg} / \mathrm{m}^{3}$
The driver from Practice Problem 13.3 fills his \(18.9-\mathrm{L}\) steel gasoline can in the morning when the temperature of the can and the gasoline is \(15.0^{\circ} \mathrm{C}\) and the pressure is 1.0 atm, but this time he remembers to replace the tightly fitting cap after filling the can. Assume that the can is completely full of gasoline (no air space) and that the cap does not leak. The temperature climbs to \(30.0^{\circ} \mathrm{C}\) Ignoring the expansion of the steel can, what would be the pressure of the heated gasoline? The bulk modulus for gasoline is $1.00 \times 10^{9} \mathrm{N} / \mathrm{m}^{2}$
The principal component of natural gas is methane \(\left(\mathrm{CH}_{4}\right) .\) How many moles of \(\mathrm{CH}_{4}\) are present in \(144.36 \mathrm{g}\) of methane?
A certain acid has a molecular mass of 63 u. By mass, it consists of \(1.6 \%\) hydrogen, \(22.2 \%\) nitrogen, and \(76.2 \%\) oxygen. What is the chemical formula for this acid?
A cylinder with an interior cross-sectional area of \(70.0 \mathrm{cm}^{2}\) has a moveable piston of mass \(5.40 \mathrm{kg}\) at the top that can move up and down without friction. The cylinder contains $2.25 \times 10^{-3} \mathrm{mol}\( of an ideal gas at \)23.0^{\circ} \mathrm{C} .$ (a) What is the volume of the gas when the piston is in equilibrium? Assume the air pressure outside the cylinder is 1.00 atm. (b) By what factor does the volume change if the gas temperature is raised to \(223.0^{\circ} \mathrm{C}\) and the piston moves until it is again in equilibrium?
