Answer: B. 0.015 mole/L
Explanation:
To calculate the number of moles for given molarity, we use the equation:
.....(1)
Molarity of solution = 0.010 M
Volume of solution = 10 mL
Putting values in equation 1, we get:
a)
1 mole of contains = 1 mol of
Thus of contain= mol of
b)
1 mole of contains = 2 mol of
Thus of contain= mol of
Total
The molar concentration of in a solution is 0.015 M
