Molarity = Moles/Liter
Use the molecular atomic mass of NaCl to convert from grams to moles.
Molecular mass of NaCl is the sum of its atomic masses. Look at the periodic table to find these. Na is 23 g/mol and Cl is 35.5 g/mol ,
so NaCl = 23 + 35.5 = 58.5 g/mol
multiply to cancel out grams
76 g NaCl * (1mol / 58.5 g NaCl) = 1.3 mol NaCl
over 1 Liter is just 1.3 M NaCl
Answer:
47.01g/mol
Explanation:
The formula of Nitrous acid is HNO₂:
The formula mass of a compound gives the sum of the atomic masses of the elements that makes up a compound.
Atomic mass of H = 1.0079g/mol
N = 14.0067g/mol
O = 15.9994g/mol
Formula mass of HNO₂ = 1.0079 + 14.0067 + 2(15.9994)
= 1.0079 + 14.0067 +31.9988
= 47.01g/mol
P is momentum f is force and m is mass
