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
Hope this helps!
Both figures are mixtures,
Figure II is a heterogenous mixture
Figure I is a homogenous mixture
A persons weight changes as he travels from earth to space but his mass remains the same
Molar mass is the mass of a given substance divided by the amount of that substance, measured in g/mol.
I wanna say 3,398.08 but let me know if that sounds very off
