Web23 jul. 2014 · Ernest Z. Jul 23, 2014. There are 0.0074 mol of Cl⁻ ions in 0.50 g of CuCl₂. The formula tells you that there are 2 mol of Cl⁻ in 1 mol of CuCl₂. So we must find the moles of CuCl₂. We must convert grams of CuCl₂ → moles of CuCl₂ → moles of Cl⁻. 0.50 g CuCl₂ × 1mol CuCl₂ 134.4g CuCl₂ × 2mol Cl⁻ 1mol CuCl₂ = 0. ... WebSince MgCl2 has one magnesium ion (Mg2+) and two chloride ions (Cl-), we can use the mole ratio to determine the number of ions present in 17.22 mol of MgCl2. Step 2/4 2. The formula weight of MgCl2 is 95.21 g/mol. Step 3/4 3. We can use Avogadro's number (6.022 x 10^23) to convert the number of moles to the number of molecules or ions. Step 4/4 4.
