<u>Answer:</u> The concentration of zinc oxalate is
<u>Explanation:</u>
To calculate the molarity of solution, we use the equation:
We are given:
Moles of zinc oxalate = (Conversion factor:
)
Volume of solution = 450 mL
Putting values in above equation, we get:
In case of multiplication and division, the number of significant digits is taken from the value which has least precise significant digits. Here, the least precise number of significant digits are 2.
Hence, the concentration of zinc oxalate is
