(a)
Interpretation:
The volume of 0.10 M NaCl containing 58.44 g NaCl needs to be determined.
Concept Introduction :
Molecular weight of NaCl is 58.44 g/mol.
Molarity of NaCl is 0.10 means there is 0.10 mol NaCl in 1 L solution.
(a)
Answer to Problem 5E
10 L of 0.10 M NaCl would contain 58.44 g NaCl.
Explanation of Solution
Molecular weight of NaCl is 55.44 g/mol.
The mass can be calculated from number of moles and molar mass as follows:
I L must contain 0.10 mole NaCl
5.844 g NaCl would be in 1L solution.
So, 58.44 g NaCl is would be in 10 L solution.
(b)
Interpretation:
The volume of 3.0 M NaCl containing 58.44 g NaCl needs to be calculated.
Concept Introduction :
Molecular weight of NaCl is 58.44 g/mol.
Molarity of NaCl is 3.0 means there is 3.0 mol NaCl in 1 L solution.
(b)
Answer to Problem 5E
0.33 L of 3.0 M NaCl would contain 58.44 g NaCl.
Explanation of Solution
Molecular weight of NaCl is 55.44 g/mol.
The mass can be calculated from number of moles and molar mass as follows:
I L must contains 3.0 mole NaCl which is equal to
Since, 175.32 g is in 1 L solution, thus, 58.44 g will be in:
So 58.44 g NaCl is would be in 0.33 L solution.
(c)
Interpretation:
The volume of 5.5 M NaCl containing 58.44 g NaCl needs to be determined.
Concept Introduction :
Molecular weight of NaCl is 58.44 g.
Molarity of NaCl is 5.5 means there is 5.5 mol NaCl in 1 L solution.
(c)
Answer to Problem 5E
0.182 L of 5.5 M NaCl would contain 58.44 g NaCl.
Explanation of Solution
Molecular weight of NaCl is 55.44 g/mol.
The mass from 5.5 mol can be calculated as follows:
Thus, 1 L of solution contains 321.42 g of NaCl.
The volume of solution containing 58.44 g of NaCl will be:

H CO₂Me 1) NaOMe 2) H3O® CO₂Mearrow_forward2. Platinum and other group 10 metals often act as solid phase hydrogenation catalysts for unsaturated hydrocarbons such as propylene, CH3CHCH2. In order for the reaction to be catalyzed the propylene molecules must first adsorb onto the surface. In order to completely cover the surface of a piece of platinum that has an area of 1.50 cm² with propylene, a total of 3.45 x 10¹7 molecules are needed. Determine the mass of the propylene molecules that have been absorbed onto the platinum surface.arrow_forwardChem 141, Dr. Haefner 2.
