how many moles of Cl in 2.7 mol CaCl2

There are two atoms Cl in 1 molecule of CaCl2; therefore, 2.7 mols CaCl2 will have 2*2.7 mols Cl.

To find the number of moles of Cl in 2.7 mol of CaCl2, we need to determine the ratio of moles of Cl to moles of CaCl2. The chemical formula for calcium chloride is CaCl2, which means there are two moles of chlorine (Cl) atoms for every one mole of calcium chloride (CaCl2).

Step 1: Determine the mole ratio
For every 1 mole of CaCl2, there are 2 moles of Cl.

Step 2: Calculate the moles of Cl
To find the moles of Cl in 2.7 mol of CaCl2, multiply the number of moles of CaCl2 by the mole ratio of Cl to CaCl2.

2.7 mol CaCl2 × (2 mol Cl / 1 mol CaCl2) = 5.4 mol Cl

Therefore, there are 5.4 moles of Cl in 2.7 moles of CaCl2.
