Question

How many moles are in 1.1 grams of fecl3

Answer 1

Molar mass of FeCl3 = 162.2 g/mol

1 mole FeCl3 -------------- 162.2 g
mole FeCl3 ---------------- 1.1 g

moles = 1.1 / 162.2

= 0.00678 moles

hope this helps!.

Answer 2

`6.83.10^(-3) mol FeCl_(3)`

Step-by-step explanation:

We have to find the molar mass of the compound.

We must multiply the atomic mass of each element of the compound by the number of atoms of each one

`FeCl_(3)`

molar mass
`FeCl_(3)`

`Fe= 56g/mol\\Cl= 35g/mol`

`FeCl_(3)= 56g/mol+3(35g/mol)=161g/mol`

We know that in 1 mol of
`FeCl_(3)` it has a mass of 161g.

Now we can find out how many moles of
`FeCl_(3)` are in 1.1 g.

`161g FeCl_3\longrightarrow 1 mol FeCl_3\\ 1.1g FeCl_3\longrightarrow x\\ x=(1.1g FeCl_3.1 molFeCl_3)/(161 g FeCl_3) = 6.83.10^(-3) mol FeCl_(3)`
