Iron dose calculation

[Cory]

If i dosed 65 mg of elemental iron into 526 liters of water, how much is there in mg/l or ppm?

Anyone know how to calculate this i tried but cant figure it out

Okay so 526,000 ml of tank water plus 65mg of iron is... so mg/l .65 mg/l of iron? Or .65ppm?

How do i convert this im so lost haha

65 mg in 526 L is 0.12 mg/L or 0.12 / 1.026 kg/L = 0.12 mg/kg (ppm)
