(a)
Interpretation:
The molar mass of N element needs to be determined.
Concept Introduction :
The molar mass of an element can be determined by looking at its
(a)
Answer to Problem 4E
Molar mass of N element is 14.007 g/mol.
Explanation of Solution
The N element belongs to group 15 of the periodic table. Its
From the periodic table, it can be seen that atomic mass of N atom is 14.007 amu. Thus, the molar mass of N will be 14.007 g/mol.
(b)
Interpretation:
The molar mass of Ne element needs to be determined.
Concept Introduction :
The molar mass of an element can be determined by looking at its atomic mass in the periodic table.
(b)
Answer to Problem 4E
Molar mass of Ne element is 20.180 g/mol.
Explanation of Solution
The Ne element belongs to group 18 of the periodic table. Its atomic number is 10. The atomic mass is approximately double the atomic number of elements in the periodic table.
From the periodic table, it can be seen that atomic mass of Ne atom is 20.180 amu. Thus, the molar mass of Ne will be 20.180 g/mol.
(c)
Interpretation:
The molar mass of Cl element needs to be determined.
Concept Introduction :
The molar mass of an element can be determined by looking at its atomic mass in the periodic table.
(c)
Answer to Problem 4E
Molar mass of Cl element is 35.453 g/mol.
Explanation of Solution
The Cl element belongs to group 17 of the periodic table. Its atomic number is 17. The atomic mass is approximately double the atomic number of elements in the periodic table.
From the periodic table, it can be seen that atomic mass of Cl atom is 35.453 amu. Thus, the molar mass of Ne will be 35.453 g/mol.
(d)
Interpretation:
The molar mass of Cu element needs to be determined.
Concept Introduction :
The molar mass of an element can be determined by looking at its atomic mass in the periodic table.
(d)
Answer to Problem 4E
Molar mass of Cu element is 63.546 g/mol.
Explanation of Solution
The Cu element belongs to group 11 of the periodic table. Its atomic number is 29. The atomic mass is approximately double the atomic number of elements in the periodic table.
From the periodic table, it can be seen that atomic mass of Cu atom is 63.546 amu. Thus, the molar mass of Cu will be 63.546 g/mol.
