Answer:
<h2>775.75 moles</h2>
Explanation:
To find the number of moles in a substance given it's number of entities we use the formula
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
We have the final answer as
<h3>775.75 moles</h3>
Hope this helps you
Consider the Chemical Reaction first:
Reaction: H₂SO₄ + 2 NaCl → 2 HCl + Na₂SO₄
Now, Given mass of NaCl = 30 g
Molar mass of Nacl = 58 g/mol
Now, Number of moles of NaCl = 30/58 = 0.517 mol
Balance the equation, For every 2 molecules of NaCl, 2 molecules of HCl formed, so the number of moles would be same.
Hence, Number of moles of HCl = 0.517 mol
Now, Mass of HCl = Molar mass of HCl * Number of moles
Mass = 36 * 0.517 [ Molar mass of HCl = 36 ]
Mass = 18.62 g
In short, Your Answer would be: 18.62 Grams
Hope this helps!
The balanced reaction is:
<span>Cu + 2AgNO3 = 2Ag + Cu(NO3)2
We are givent the amount of silver to be produced. This will be the starting point. Calculations are as follows:
</span><span> 3.50 mol Ag ( 1 mol Cu / 2 mol Ag ) = 1.75 mol Cu
</span>
Therefore, we need 1.75 mol of copper in order to produce 3.50 mol of silver.
