B.) Copper
The alkaline battery gets its call because of the fact it has an alkaline electrolyte of potassium hydroxide, as adverse to the acidic electrolyte of the zinc-carbon batteries that are presented interior the same nominal voltages and actual length.
Answer:
12.5%
Explanation:
Given data:
Volume/Volume % = ?
Volume of solute = 25 mL
Volume of solution = 200 mL
Solution:
Formula:
v/v% = ( volume of solute / volume of solution ) × 100
by putting values,
v/v% = ( 25 mL / 200 mL) × 100
v/v% = 0.125 × 100
v/v% = 12.5%
