Mole Conversion: How many atoms are in 0.830 moles of gold? ​
denis23 [38]

Answer:

<h2>4.99 × 10²³ atoms</h2>

Explanation:

The number of atoms of gold can be found by using the formula

<h3>N = n × L</h3>

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 = 0.83 × 6.02 × 10²³

We have the final answer as

<h3>4.99 × 10²³ atoms</h3>

Hope this helps you

what is the freezing point of a 0.195m aqueous solution of K2S? (Report amount to three decimal points)
Solnce55 [7]
The freezing point depression of water is 1.86°C/m.kg 
<span>K2S dissociates: </span>
<span>K2S ↔ 2K+ + S 2- </span>
<span>1mol K2S will produce 3 mol of ions. </span>
<span>Therefore in the freezing point equation: i = 3 </span>
<span>Depression of freezing point = Kf * i* m </span>
<span>Depression of freezing point = 1.86*3*0.195 </span>
<span>Depression of freezing point = 1.088°C </span>
<span>The solution will freeze at - 1.088°C </span>
