Answer:

Everyone, this is Ricky. And today we're working on Problem 51 from Chapter 22 and we're gonna determine the number of UNP. Aired electrons for the complex island of CEO seal for minus two I first up, let's determine the charge of art metal ion. So cue is our charge plus four minus one, which is a charge of each chloride ion. The overall charge of minus two Hugh is equal to plus two. I hope this will help

How many molecules of Ca are found in a sample with 0.2 mols?

DochEvi [55]

Answer:

$\boxed{1.2 \times 10^{23}\text{ atoms}}$

Explanation:

6.023 × 10²³ atoms of Ca are in 1 mol of Ca

$\text{No. of atoms} = \text{0.2 mol} \times \dfrac{6.023 \times 10^{23}\text{atoms }}{\text{1 mol }} = \mathbf{1.2 \times 10^{23}} \textbf{ atoms}}\\\\\text{There are }\boxed{\mathbf{1.2 \times 10^{23}} \textbf{ atoms}} \text{ atoms in 0.20 mol of Ca}$
