a) How many micrometers make 0.4 m?
b)How many µg in 4.732 mg?
well, a million micrometers make up a meter, so here, I bet 400,000
Lets see: .4m*10^6micrometers/meter=.4*10^6=4*10^5.
4.732mg*1000microgram/milligram=4732 micrograms
b)How many µg in 4.732 mg?
Lets see: .4m*10^6micrometers/meter=.4*10^6=4*10^5.
4.732mg*1000microgram/milligram=4732 micrograms
