How many atoms are there in 1.45 x 10^-17 mol of arsenic?

To find the number of atom we multiply the

No.of moles number of mole with Avogadro's number.

As 1mole of arsenic contains contains 6.02x10^23 unit of substance which is a constant value e for 1mooe

So;

1.45x10^-17moles contain=6.02x10^23 multiply with 1.45x10^-17

= 8,730,000 atoms of arsenic are present in above mentioned moles of arsenic

if you mean hydrogen and oxygen then water is the product

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.
