Answer:
83 3/10
Step-by-step explanation:
multiple the numbers
The weight of copper is 8 1/10 in the gram.
I add 2x + 3x to get 13 1/2 to find what x is to multiply back into the ratio to find the weight of copper.
So the equation is 5x=13 1/2
Solving it we get x=27/10.
Now we multiply 27/10 * 3 to find the weight of copper. The answer is 81/10, simplifying into 8 1/10. This means that the weight of Zinc is 5 2/5, we get this by subtracting 13 1/2 to 8 1/10.
Hope this helps!
Note that:
Micro = 1e + 6 of a meter
Nano = 1e + 9 of a meter
Centi = 100 of a meter
Milli = 1000 of a meter
In this case, nano, or (B) is your answer
hope this helps
