Calculate the concentration of the dye Blue #1 if 0.1018.g are dissolved in 100.00mL of water. The molar mass of Blue #1 is 792.86 g/mol.

Answer 1

Concentration can be in g/ml, mg/ml, moles/liter, etc. The question doesn't specify the desired units.

0.1018 g / 100.00 ml = 0.001019 g / ml

0.1018 g / 100 ml x 1 mol / 792.86 g / mol x 1000 ml / L = 0.0012840 mol / L = 0.0012840 M
