Calculate the molecules of oxygen gas in 20.6 moles. Round to 3 significant figures.

1.24 × 10²⁵ molecules of oxygen gas

Explanation:

Step 1: Given data

Moles of oxygen gas: 20.6 moles

Step 2: Calculate the number of molecules present in 20.6 moles of oxygen gas

In order to convert moles to molecules, we need a conversion factor. In this case, we will use Avogadro's number: there are 6.02 × 10²³ molecules in 1 mole of molecules.

20.6 mol × 6.02 × 10²³ molecules/1 mol = 1.24 × 10²⁵ molecules

3 hours because it is a decent distance.

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates
