HOW MANY MOLES IS 1.50*10 TO THE 23RD POWER MOLECULES NH3

To determine the number of moles of NH3 molecules, you need to use Avogadro's number and the formula for moles. Here's how you can calculate it:

Step 1: Determine Avogadro's number
Avogadro's number, denoted by "Na," is equal to 6.022 × 10^23. This constant represents the number of particles in one mole of a substance.

Step 2: Convert molecules to moles
Divide the given number of molecules (1.50 × 10^23) by Avogadro's number to convert it into moles.

1.50 × 10^23 molecules NH3 / (6.022 × 10^23 molecules/mol)
= (1.50 × 10^23) / (6.022 × 10^23) mol NH3

Step 3: Perform the calculation
To simplify the calculation, divide the given number (1.50) by Avogadro's number (6.022) and then multiply it by 10^23:

(1.50 / 6.022) × 10^23
≈ 0.249 mol NH3 (rounded to three decimal places)

Therefore, there are approximately 0.249 moles of NH3 in 1.50 × 10^23 molecules of NH3.
