An ayurvedic drug, is found to contain 400 ppm of
colloidal gold. Mass % of gold (atomic mass of Au
= 197) will be.
solution : 1ppm full form : 1 part per million. means in 10^6 g solution contains 1g of solute.
a/c to question,
An Ayurvedic drug is found to contain 400 ppm of colloidal gold.
it means, 10^6g drug contains 400g of colloidal gold.
now, mass percentage of gold = mass of gold/mass of drug × 100
= 400g/10^6g × 100
= 4 × 10^4/10^6
= 4/100
= 0.04%
hence, answer is 0.04%
