Question

How many atoms are in 0.075 mol of titanium?

O 4.5 x 1022
O 1.2 x 10-25
O 6.4 x 102
O 2.2 x 1024

Answer 1

The answer is

4.5 × 10²²

Step-by-step explanation:

To find the number of atoms of titanium , given it's number of moles we use the formula

N = n × L

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question

n = 0.075 mol

We have

N = 0.075 × 6.02 × 10²³

We have the final answer as

4.5 × 10²²
