When the pressure and temperature are held constant, the volume of a gas is inversely proportional to the number of miles presen
2 answers:
<u>Answer:</u>
The given statement is false.
<u>Explanation:</u>
As per Avogadro’s law under constant temperature and pressure there will be same amount of moles present in the same volume of gas. If the gas increases, the amount of moles also increases. In other words we can say that the volume of gas(V) is directly proportional to the number of moles present (n). So we can say,
The amount of moles is called Avogadro’s constant.

Answer:
0.2042 M is the original concentration of (aq) in the titrating solution.
Explanation:
Mass of = 0.217 g
Moles of
1 mole of have 2 mole of As and 1 mole of
have 1 mole of As.
So, from 1 mole of we will have 2 moles of
Then from 0.001096 mol of :
of
According to reaction, 1 mole of reacts with 2 mole of cerium (IV) ions,then 0.002192 mol of
of cerium (IV) ions.
Volume of the acidic cerium{IV) sulfate = 21.47 ml =0.02147 L
1 mL = 0.001 L
0.2042 M is the original concentration of (aq) in the titrating solution.
