The SI unit of mass is the kilogram, regardless of what something is made of.
The atomic mass unit (amu) is a unit of mass used to express the average mass of an atom or molecule. To calculate the atomic mass unit of gold (Au), you would look at the atomic mass of gold on the periodic table, which is approximately 197 amu.
The atomic mass of Gold (Au) is 196.9665 grams per mole.
No, AU stands for astronomical unit
AU is short for astronomical unit. 1 AU is about 93 million miles, which is the distance between Earth and the sun.
1 astronomical unit (AU) is approximately 93 million miles.
AU - Astronomical Unit, is a unit for distance, and can't be used to measure mass.

1 astronomical unit (AU) is approximately 93 million miles.
The conversion factor for the keyword "au" unit in astronomical measurements is 1 astronomical unit (au) is equal to approximately 149.6 million kilometers.
To find the number of moles in 355 grams of Au, you need to divide the given mass by the molar mass of gold (Au). The molar mass of Au is approximately 197 grams/mol. Therefore, 355 grams of Au is equivalent to 355/197 = approximately 1.80 moles of Au.
Astronomical Unit
It is the earth that is in orbit one astronomical unit (AU) from the sun. That's where the AU came from. One AU is the mean distance from the sun to the earth. A link can be found below.
Gold is a metal element. atomic number of it is 79.
To find the mass of 3.34 moles of gold atoms, you need to multiply the number of moles by the molar mass of gold. The molar mass of gold is 196.97 g/mol. Therefore, the mass of 3.34 moles of gold atoms is 3.34 moles * 196.97 g/mol = 658.5 grams.
