Molarity refers to the MOLES of solute per litre of solvent. We're given a volume of solvent, but a mass of solute. We need to convert mass to moles, and the way to do that is using the molar mass of the solute. This question can't be answered unless we know the molar mass of the solute.

7. How many moles are in 18.00 x 1023 particles of AICIZ?

Andrej [43]

Answer:

<h3>The answer is option A</h3>

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

$n = \frac{N}{L} \\$

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 we have

$n = \frac{18.0 \times {10}^{23} }{6.02 \times {10}^{23} } = \frac{18}{6.02} \\ = 2.99003322...$

We have the final answer as

<h3>2.99 moles</h3>
