Answer:
2000 mg
Explanation:
It is given that, the human body normally excretes about 2.0 g of potassium per day via the urine. We need to find the mass of potassium in mg i.e. milligram
We know that,
1 gram = 1000 milligram
To convert 2 gram to mg, it can be done as follows :
2 gram = 1000 × 2 mg
= 2000 mg
Hence, the mass of potassium is 2000 mg.
