Answer:
4.90 moles of will produce (9.8) moles of
,
(4.90) moles of and
(39.2) moles of
Explanation:
From the question we are told that
The number of moles of is
The formation reaction of is
From the reaction we see that
1 mole of is formed by 2 moles of
1 mole of
and 4
This implies that
4.90 moles of will produce (2 * 4.90) moles of
,
(1 * 4.90) moles of and
(8 * 4.90) moles of
So
4.90 moles of will produce (9.8) moles of
,
(4.90) moles of and
(39.2) moles of
Answer: The of a solution is
M
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.
where,
n = moles of solute
= volume of solution in ml
moles of =
Now put all the given values in the formula of molality, we get
pH or pOH is the measure of acidity or alkalinity of a solution.
According to stoichiometry,
1 mole of gives 1 mole of
Thus moles of
gives =
moles of
Putting in the values:
Thus the of a solution prepared by dissolving 0.0912 g of hydrogen chloride in sufficient pure water to prepare 250.0 ml of solution is
M
