Answer:
Q= 0.21472 C
Explanation:
current is the rate of flow of charge through a wire or a circuit.
I = Q/t
Where I is current
Q is charge
t is time
Q=It
from the question, I=0.52 A , t=411 milliseconds
Q = 0.52 *411*
Q= 0.21472 C
Explanation:
I hope this helps Chemistry is so hard and I hate it

Answer:
Percentage of copper = 88%
Explanation:
Given data:
Mass of copper = 51.2 g
Mass of tin = 6.84 g
Percentage of copper = ?
Solution:
Formula:
Percentage of copper = mass of copper / total mass × 100
Now we will determine the total mass:
Total mass = mass of copper + mass of tin
Total mass = 51.2 g + 6.84 g
Total mass = 58.04 g
Now we will calculate the percentage of copper.
Percentage of copper = 51.2 g / 58.04 g × 100
Percentage of copper = 0.88 × 100
Percentage of copper = 88%
