A period in the periodic table is a horizontal row. All elements in a row have the same number of electron shells. Each next element in a period has one more proton and is less metallic than its predecessor.
Answer:
M = 63.02g/mol
Explanation:
Molar mass = the atomic masses of each atom combined
H = 1.01
N = 14.01
O = 16.00
M = 1.01(1) + 14.01(1) + 16.00(3)
M = 63.02
Therefore the molar mass of nitric acid is 63.02g/mol
