Volume Calculation of Copper(II) Nitrate Solution

How can we calculate the volume of a 0.944M copper(II) nitrate solution that will contain 15.6 g of the compound?

What steps are involved in determining the volume of the solution?

Answer:

To calculate the volume of a 0.944M copper(II) nitrate solution that will contain 15.6 g of the compound, we need to follow these steps:

First, we must calculate the number of moles of copper(II) nitrate using the formula: moles = mass / molar mass.

The molar mass of copper(II) nitrate (Cu(NO3)2) is calculated by summing the atomic masses of its elements:

Cu: 63.55 g/mol

N: 14.01 g/mol

O: 16.00 g/mol

Next, calculate the moles of copper(II) nitrate: moles = 15.6 g / molar mass of Cu(NO3)2.

Then, use the molarity formula to calculate the volume (in liters) of the solution: volume (in L) = moles / molarity.

Convert the volume to milliliters by multiplying the volume in liters by 1000.

By performing these calculations, we can determine the volume of the 0.944M copper(II) nitrate solution that will contain 15.6 g of the compound.
