Answer:
1.53 mol CaCl2.
Step-by-step explanation:
To convert from moles of NaCl to moles of CaCl2 using the given equation, we need to use stoichiometry.
From the equation, we can see that for every 1 mole of CaCl2, we need 1 mole of NaCl. Therefore, the number of moles of CaCl2 is equal to the number of moles of NaCl:
1.53 mol NaCl = 1.53 mol CaCl2
So the answer is 1.53 mol CaCl2.
