Step-by-step explanation:
NaCl to CaCl2 Conversion
Convert 4.74 mol NaCl to moles of CaCl2, using the equation given below. Round to the nearest 0.01, and remember to include units (properly abbreviated) and substance in your answer! Na3PO4 + CaCl2 --> Ca3(PO4)2 + NaCl
The balanced chemical equation provided relates the moles of NaCl and CaCl2 indirectly via a chemical reaction. To use it, we need to first determine the mole ratio between NaCl and CaCl2 from the coefficients in the equation.
From the equation:
1 mol of Na3PO4 produces 3 moles of CaCl2
1 mol of Na3PO4 produces 2 moles of NaCl
Thus, we can say that for every 2 moles of NaCl produced, 3 moles of CaCl2 are consumed. This ratio can be used to convert 4.74 mol of NaCl to moles of CaCl2.
First, we'll convert the 4.74 mol of NaCl to moles of Na3PO4 using the mole ratio between NaCl and Na3PO4.
2 moles NaCl/1 mole Na3PO4
4.74 mol NaCl * (1 mol Na3PO4 / 2 mol NaCl) = 2.37 mol Na3PO4
Next, we'll use the mole ratio between Na3PO4 and CaCl2 to convert moles of Na3PO4 to moles of CaCl2.
3 moles CaCl2/1 mole Na3PO4
2.37 mol Na3PO4 * (3 mol CaCl2 / 1 mol Na3PO4) = 7.11 mol CaCl2
Therefore, 4.74 mol of NaCl is equivalent to 7.11 mol of CaCl2. Rounded to the nearest 0.01, the answer is:
7.11 mol CaCl2 (properly abbreviated as moles of CaCl2)
