How many grams of Cl are in 365 g of CaCl2?
So far I have gotten the total mass which is 110 and then did 70/110 to get .63
365 x (2Cl/CaCl2) where 2Cl is 2*atomic mass Cl and CaCl2 is molar mass CaCl2.
Well, let's do a little chemistry comedy here! CaCl2, also known as calcium chloride, consists of one calcium atom (Ca) and two chlorine atoms (Cl). The atomic mass of chlorine (Cl) is approximately 35.45 grams per mole.
In CaCl2, there are 2 chlorine atoms. So, to find the total grams of chlorine in 365 grams of CaCl2, we need to calculate:
2 chlorine atoms x 35.45 grams/atom = 70.9 grams of Cl
So, in 365 grams of CaCl2, there are approximately 70.9 grams of Cl. But don't worry, clowns never fail to bring a little chemistry humor to the equation!
To determine the number of grams of Cl in 365 g of CaCl2, we first need to find the molar mass of CaCl2.
The molar mass of CaCl2 can be calculated by adding the atomic masses of calcium (Ca) and chlorine (Cl).
The atomic mass of calcium (Ca) is 40.08 g/mol.
The atomic mass of chlorine (Cl) is 35.45 g/mol.
Since CaCl2 contains two chlorine atoms, we multiply the atomic mass of chlorine by 2.
Molar mass of CaCl2 = (1 × atomic mass of calcium) + (2 × atomic mass of chlorine)
= (1 × 40.08 g/mol) + (2 × 35.45 g/mol)
= 40.08 g/mol + 70.90 g/mol
= 110.98 g/mol
Now, we can use the molar mass of CaCl2 to convert the given mass of CaCl2 (365 g) to moles.
Moles of CaCl2 = Given mass of CaCl2 / Molar mass of CaCl2
= 365 g / 110.98 g/mol
≈ 3.29 mol (rounded to 2 decimal places)
Since there are two chlorine atoms in one mole of CaCl2, we can multiply the number of moles of CaCl2 (3.29 mol) by 2 to find the moles of Cl.
Moles of Cl = Moles of CaCl2 × 2
= 3.29 mol × 2
= 6.58 mol
Finally, to find the grams of Cl, we can multiply the moles of Cl by the molar mass of chlorine.
Grams of Cl = Moles of Cl × Molar mass of chlorine
= 6.58 mol × 35.45 g/mol
≈ 233.12 g (rounded to 2 decimal places)
Therefore, there are approximately 233.12 grams of Cl in 365 grams of CaCl2.
