Answer: there are 0.024 moles of CCl4 present in 3.70 grams of this compound
Explanation: To determine the number of moles of a compound present in a given mass, we can use the formula:
moles = mass / molar mass
where molar mass is the mass of one mole of the compound and is measured in g/mol.
The molar mass of carbon tetrachloride (CCl4) is 153.82 g/mol.
So to find the number of moles of CCl4 present in 3.70 grams, we can plug in the values into the formula:
moles = 3.70 g / 153.82 g/mol
moles = 0.024 mol
Therefore, there are 0.024 moles of CCl4 present in 3.70 grams of this compound.
