in one experiment, 0.3030 g of erythrosin b (M = 879.9 g/mol) was added to enough water to make 100.0 mL of solution A. 5.00 mL of solution A was added to enough water to make 100.0 mL of solution B. Finally, 5.00 mL of solution B was added to enough water to make 100.0 mL of solution C. What was the concentration of Erythrosin B in solutions A, B, and C?
