How many moles of Cl2 molecules are in 985g of Cl2 What is the mass of Cl2 atoms present?
To find the number of moles of Cl₂ in 985 g, use the molar mass of Cl₂, which is about 70.906 g/mol. The number of moles is calculated by dividing the mass by the molar mass: [ \text{moles of Cl₂} = \frac{985 \text{ g}}{70.906 \text{ g/mol}} \approx 13.9 \text{ moles} ] Since Cl₂ consists of two chlorine atoms, the mass of Cl atoms present can be calculated by multiplying the moles of Cl₂ by 2 and then by the molar mass of chlorine (approximately 35.453 g/mol), resulting in approximately 985 g of Cl atoms.

How many moles of Cl are in 5.0g of chloral hydrate?
Assuming that you are talking about Chloral Hydrate as in (C2H3Cl3O2) this shouldn't be too hard to answer. We are give 5.0g of C2H3Cl3O2 so we need to convert that into atoms, then moles. First set up the equation 5.0g*1mole/165.40g [<-molar mass] *6.02x10^23 molecules / 1 mole*3atoms Cl/1molecule. [You should get 5.46x10^22] If you solve that, you will come up with the total number of Cl atoms in C2H3Cl3O2 so from there just convert that into moles using avagadro's number 5.46x10^22atoms Cl/1*1mole/6.02x10^23atoms
