Answer:
0.0957 M
Explanation:
Equivalence appears to occur upon addition of 20 mls of 0.0957 M HCl.
0.02 L x 0.0957 mole/L = 0.001914 moles HCl added
CH3NH3 + HCl ==> CH3NH4^+ Cl^-
Molarity of CH3NH3 initially present = 0.0957 M
pH < 7 because the reaction is between a strong acid (HCl) and a weak base (methylamine)
It’s tooo barely I cannot see it
<u>Answer:</u> The solubility of nitrogen gas at 5.00 atm is
<u>Explanation:</u>
To calculate the molar solubility, we use the equation given by Henry's law, which is:
Or,
where,
are the initial concentration and partial pressure of nitrogen gas
are the final concentration and partial pressure of nitrogen gas
We are given:
Putting values in above equation, we get:
Hence, the solubility of nitrogen gas at 5.00 atm is
