Question

1.93 g sample of soil was analyzed and found to contain 3.6 μg Fe. What is the
concentration of Fe in the soil in ppm and in ppb? (03)

Answer 1

Answer:

$\huge{\mathfrak{Answer:-}}$

An integrated approach was performed on the soil, plant-crops and groundwater system at the Thiva basin, to evaluate the extent and intensity of the heavy metal contamination, the percentage of metals transferred into plants/crops (bio-accumulation) and the potential sources of contamination.

Answer 2

Answer:

Explanation

first collect data

data$ppm=microgram/gram in solids\\ppm=microgram/ml in liquids$

mass of sample:1.93g

mass of iron:3.6micro gram

so the formula for ppm is analyse/sample. in this case our anaylse is iron and our sample is 1.93 so it will be written like this

ppm=3.6/1.93

=1.86microgram per gram.
