Determine the number of moles in 3.13 × 10²³ formula units of MgCl₂.
love history [14]

Answer:

<h2>0.52 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{3.13 \times  {10}^{23} }{6.02 \times  {10}^{23} }  =  \frac{3.13}{6.02}  \\  = 0.519933

We have the final answer as

<h3>0.52 moles</h3>

Hope this helps you

Consider the following reversible reaction. What is the equilibrium constant expression for the given system?
ladessa [460]
The question is incomplete. Complete question is attached below
..........................................................................................................................

Answer: 
Equilibrium constant (K) is defined as the ratio of concentration of product to concentration of reactant.

For the reaction:  2H2O(g)    ↔     2H2(g)      +       O2(g)

Equlibrium constant = \frac{[H_2]^2[O_2]}{[H_20]^2}

[ ] bracket in above expression indicates concentration.
