Question

An MP3 player draws a current of 0.120 ampere

Answer 1

     The Definition of Electrical Current is given by:

$i= \frac{\Delta Q}{\Delta t}$
 
     Entering the unknowns:

$i= \frac{\Delta Q}{\Delta t} \\ \Delta Q=0.12*900 \\ \boxed {\Delta Q=108C}$

Number 2

If you notice any mistake in my english, please let me know, because i am not native.

Answer 2

Answer: (2) 108 C

Explanation:

Electric charge of 1 coulomb has said to have passed when a current of 1 Ampere is passed for 1 second.

$Q=I\times t$

Q= charge in coloumb = ?

I = current in amperes = 0.120 A

t= time in seconds = 900 sec

$Q=0.120A\times 900sec=108C$
