Answer is provided. All I need is solution. Thank you

From the following formula, calculate the quantities required to make 5 lb of hydrophilic ointment.

Methylparaben                                              0.25 g

Propylparaben                                               0.15 g

Sodium lauryl sulfate                                       10 g

Propylene glycol                                             120 g

Stearyl alcohol                                                250 g

White petrolatum                                          250 g

Purified water, ad                                        1000 g

 

Answer: 0.568 g methylparaben

                0.341 g propylparaben

                22.7 g sodium lauryl sulfate

                272.4 g propylene glycol

                567.5 g stearyl alcohol

                567.5 g white petrolatum

                  ad 2270 g or 5 lb purified water
