number of moles of Cl in 2.7 mol CaCl2
5.4
There are two atoms of Cl in 1 mole of CaCl2; therefore, 2.7 mol CaCl2 must have 2*2.7 moles Cl.
To find the number of moles of chlorine (Cl) in 2.7 moles of calcium chloride (CaCl2), we need to consider the mole ratios in the chemical formula of calcium chloride.
The chemical formula of calcium chloride is CaCl2, which indicates that each formula unit of calcium chloride contains one calcium atom (Ca) and two chlorine atoms (Cl).
From this information, we can determine the number of moles of chlorine in 2.7 moles of calcium chloride by using the mole ratio:
Number of moles of Cl = 2.7 moles CaCl2 × (2 moles Cl / 1 mole CaCl2)
Simplifying this calculation, we have:
Number of moles of Cl = 2.7 moles × 2 = 5.4 moles
Therefore, there are 5.4 moles of chlorine in 2.7 moles of calcium chloride.
To determine the number of moles of Cl in 2.7 mol of CaCl2, you need to consider the molar ratio between CaCl2 and Cl.
The chemical formula of CaCl2 indicates that for every 1 molecule of CaCl2, there are 2 moles of Cl. This means that the molar ratio between CaCl2 and Cl is 1:2.
To find the number of moles of Cl in 2.7 mol of CaCl2, you can use the molar ratio:
Number of moles of Cl = Number of moles of CaCl2 × Ratio of moles of Cl to CaCl2
Number of moles of Cl = 2.7 mol × 2 mol Cl / 1 mol CaCl2
Number of moles of Cl = 5.4 mol
Therefore, there are 5.4 moles of Cl in 2.7 moles of CaCl2.
