Initial volume of the balloon = = 348 mL
Initial temperature of the balloon =
Final volume of the balloon = 322 mL
Final temperature of the balloon =
According to Charles law, volume of an ideal gas is directly proportional to the temperature at constant pressure.
On plugging in the values,
Therefore, the temperature of the freezer is 276 K
Answer:
Two moles.
Explanation:
Sulphuric (sulfuric) acid is a diprotic acid. When one mole of
molecules dissolve in water, two moles of
ions would be produced.
.
On the other hand, sodium hydroxide is a monoprotic base. When one mole of
formula units dissolve in water, only one mole of hydroxide ions
would be produced.
.
Note that and
react at a one-to-one ratio:
.
As a result, it would take of
to react with the
of
that was released when
of
is dissolved in water. Since one mole of
formula units could produce only one mole of
, it would take
of
formula units to produce that
of
for reacting with
of
.
