Answer:
volume=0.4ml
Explanation:
use the equation
n=c×v. first make v become the subject of the formula by dividing c on both sides of the equation
v=n/c
v=0.100÷2.5×10^-2
v=4×10^-4
v=0.0004L
now convert 0.0004L to ml by multiplying 0.0004 with 1000 to get 0.4ml
therefore the volume in ml is 0.4ml
