2)How many picograms are in 10mg? in 38ng?
3) How many microlitres are in 2L? in 50mL?
2)How many picograms are in 10mg? in 38ng?
3) How many microlitres are in 2L? in 50mL?

(1) 1 angstrom = 10^-10m or 1/10 x 10^-9m = 1/10 nm
(2) 1 picogram = 10^-12g
So, 10mg = 10/1000g = 10^-2g will have (1/10^-12) x 10^-2 = 10^10 picograms.
Again 38ng = 38 x 10^-9g will have (1/10^-12) x 38 x 10^-9 = 3.8 x 10^4 picograms.
(3) 1 microlitre = 10^-6 liters
so, 2 liters = (1/10^-6) x 2 = 2 x 10^6 microliters
50ml = 50/1000 liters will have (1/10^-6) x (50/1000) = 5 x 10^4 microliters
(2) 1 picogram = 10^-12g
So, 10mg = 10/1000g = 10^-2g will have (1/10^-12) x 10^-2 = 10^10 picograms.
Again 38ng = 38 x 10^-9g will have (1/10^-12) x 38 x 10^-9 = 3.8 x 10^4 picograms.
(3) 1 microlitre = 10^-6 liters
so, 2 liters = (1/10^-6) x 2 = 2 x 10^6 microliters
50ml = 50/1000 liters will have (1/10^-6) x (50/1000) = 5 x 10^4 microliters
