How many molecules are in 0.1 moles of oxygen gas (O2)? (2021)
Step 1: Understand that 1 mole of any substance contains a specific number of molecules, known as Avogadro's number, which is approximately 6.022 x 10^23.
Step 2: Identify how many moles of oxygen gas (O2) you have. In this case, you have 0.1 moles.
Step 3: Use the formula to find the number of molecules: Number of molecules = moles x Avogadro's number.
Step 4: Plug in the values: Number of molecules = 0.1 moles x 6.022 x 10^23 molecules/mole.
Step 5: Calculate the result: 0.1 x 6.022 x 10^23 = 6.022 x 10^22 molecules.
