Molarity
Te mean of 5, 5, 1, 1, and 3 is 3.
Mean has only 1 syllable.
If you mean (5*10)^-1 that is 1/50 If you mean 5*10^-1 that is 1/2

gmol-1 refers to grams per mole and is a unit of measurement commonly used in chemistry to express molar mass or molecular weight. It represents the mass of one mole of a substance in grams.
n = gmol = N molecules / N Avogadro n = ( 2.4 x 10^23 molecules ) / ( 6.022 x 10^23 molecules per gmol ) n = 0.3985 gmol m = ( n ) ( M ) m = ( 0.3985 ) ( 141.94 g per gmol ) = 56.6 g <----------------------

The percent of lead in lead(IV) oxide can be calculated by first determining the molar mass of lead(IV) oxide (PbO2) and then calculating the molar mass of lead in that compound. Finally, divide the molar mass of lead by the molar mass of PbO2 and multiply by 100 to get the percentage. Molar mass of lead = 207.2 g/mol and molar mass of PbO2 = 239.2 g/mol, so the percentage of lead in lead(IV) oxide is (207.2/239.2) x 100 ≈ 86.5%.
