<u>Answer:</u> The molar concentration of ammonia is 3.008 M
<u>Explanation:</u>
To calculate the concentration of base, we use the equation given by neutralization reaction:
where,
are the n-factor, molarity and volume of acid which is
are the n-factor, molarity and volume of base which is
We are given:
Putting values in above equation, we get:
Hence, the molar concentration of ammonia is 3.008 M
Answer:
To react with 0.5 moles of Zn 1 mole of HCl is required
Explanation:
Given data:
Number of moles of Zn = 0.50 mol
Number of moles of HCl = ?
Chemical equation:
Zn + 2HCl → H₂ + ZnCl₂
Now we will compare the moles of Zn and HCl through balance chemical equation.
Zn : HCl
1 : 2
0.50 : 2×0.5 = 1 mol
In order to react with 0.5 moles of zinc 1 mole of HCl is required.
Equal is the answer
