If you have 5.42 x 1024 aluminum atoms, approximately how many moles is that

sattari [20]

Answer:

<h2>9.00 moles</h2>

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

$n = \frac{5.42 \times {10}^{24} }{6.02 \times {10}^{23} } \\ = 9.0033$

We have the final answer as

<h3>9.00 moles</h3>

Hope this helps you

What is the concentration of a solution in which 10.0 g of AgNO, is dissolved in 450 mL of solution?

Rufina [12.5K]

Answer:

M=0.15

Explanation:

138 g AgNO -> 1 mol AgNO

10 g AgNO -> x

x= (10 g AgNO * 1 mol AgNO)/138 g x=0.07 mol AgNO

450 mL=0.45 L

M= mol solute/L solution

M= 0.07 mol AgNO/0.45L

M=0.15
