Yes, because is a mineral composed primarily of sodium chloride
%yield = 91.8
<h3>Further explanation</h3>
Given
20 g NaCl
45 g AgCl
Required
%yield
Solution
Reaction
NaCl + AgNO₃ ⇒ AgCl + NaNO₃
mol NaCl :
= mass : MW
= 20 g : 58,44 g/mol
= 0.342
mol AgCl from equation :
= 1/1 x mol NaCl
= 1/1 x 0.342
= 0.342
Mass AgCl(theoretical) :
= mol x MW
= 0.342 x 143,32 g/mol
= 49.02 g
%yield = (actual/theoretical) x 100%
%yield = (45/49.02) x 100%
%yield = 91.8
Answer:
101.4pKa
Explanation:
Given parameters:
Initial Volume of helium = 3.20L
Final pressure of helium = 59kPa
Final volume on helium gas = 5.5L
Unknown:
Initial pressure exerted on the balloon = ?
Solution;
To solve this pressure - volume problem, we simply apply the Boyle's law.
It states that "the volume of a fixed mass gas varies inversely as the pressure changes if the temperature is constant".
Mathematically;
P1 V1 = P2 V2
Now, insert parameters and solve;
P1 x 3.2 = 59 x 5.5
P1 = 101.4pKa
