a. 7.77x1024 atoms

b. 2.14x10-23 atoms

c. 6.02x1023 atoms

d. 1.38x1023 atoms

Given :

12.9 mol of Au.

To Find :

How many atoms are in 12.9 moles Au.

Solution :

We know, 1 mol of any element/molecules contains .

Number of atoms in 12.9 moles of Au is :

Therefore, number of atoms in 12.9 moles of Au is .

Hence, this is the required solution.

because natural gas is colorless, odorless, and tasteless, distributors add mercaptan (a chemical that smells like sulfur) to give natural gas a distinct unpleasant odor (it smells like rotten eggs). they locate the types of rock that are likely to contain natural gas deposits.

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".
