    Chemistry PPM

    .....The maximum amount of nitrate ion is 10ppm for infants.

    a) if an infant has 4.0Kg weight, how much of nitrate ion can he consume?


    This is what I did:

    Mass of Nitrate = 4.0kg * 10mg/1kg
    = 40mg

    10mg/1kg is equivilant to 10 ppm as i believe.


    Any help is really appreciated! I have no idea what to do because I had a supply teacher today that did not teach this to us, and yes I will ask my teacher for help tomorrow.

    Re: Chemistry PPM

    Since the calculation is based on mass I believe you are correct in assuming mg/kg = ppm

    If the allowance is 10mg per kg weightper day then the infant can consume 40 mg per day
