I just need help figuring out the values to do a calculation. Part of the lab relevant... "Prepare standards on the same day they will be used. Using a 100 mL volumetric flask, add x mL (vide infra) of the 0.050 mg/mL phosphate standard, 20 mL of th e molybdate-antimoney reagent, 1 mL of ascorbic acid, and dilute to volume with ultrapure water. Do this procedure for x = 0 mL, 1 ml, 2 ml, 5 ml, and 10 ml using volumetric pipettes. To be clear, we will be making 5 different solutions. The equation that was given was Concentration of initial standard (mg/mL) multiplied by volume added (mL) = concentration of created standard multiplied by volume of volumetric I dont need you to do the calculations, I just need help finding what values go in equation. we are trying to find the concentration of created standard
