A 0.000333 g sample of fluorescein is dissolved in 225 mL solution of ethanol. The molar mass of fluorescein is 332.32 g/mol and the density of ethanol is 0.785 g/mL. Required:a. What is the concentration of the solution in molarity?b. What is the concentration of the solution in ppm?

Thank you so so much for the points

6.4 cm (max) - 25 cm (min)

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
