Answer:
2.86mol/L
Explanation:
Given parameters:
Number of moles of MgCl₂ = 7.15moles
Volume of solution = 2.50L
Unknown:
Molarity of the MgCl₂ solution = ?
Solution:
The molarity of a solution is the number of moles of solute found in a given volume.
Molarity =
Insert the parameters and solve;
Molarity = = 2.86mol/L
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
