Answer:
Explanation:
It is given that pH of .
Now, molality of , M=
Now, we know,
...1
Here C is concentration.
Now,
Putting all values in equation 1.
We get,
Hence, this is the required solution.
KI-starch paper allows the detection of strong oxidizers such as nitrite. It is used here to control diazotization of 4-nitroaniline. Nitrite oxidizes potassium iodide in order to form elemental iodine which reacts with starch to a blue-violet complex. With KI-starch paper, enough sodium nitrite is added to produce nitrous acid, which <span>then will react with 4-nitroaniline to form a diazonium salt.</span>
Answer: molecules of
Explanation:
According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number of particles.
To calculate the moles, we use the equation:
1 mole of contains = molecules
0.128 mole of contains = molecules
Thus there are molecules of
