Answer:
the molecular formula = SF6
Step-by-step explanation:
firstly we have to list the firmulas we r goin to use to work out the molecular formula.
- n=mass of compound ÷mass of empirical formula
- molecula formula=n×empirical formula
now we use the 1st formula to find n which will be substituted into the molecular formula
We are going to take the mass we have been given in the question as the mass of the compound and substitute it to the formula.
Then we will work out the mass of empirical formula for the compound: Sulphur; 32 flourine;19 SF6_ 32+6(19)=146
now we finish off n
- n=146.06÷146=1.000410959
- n=1
Lastly we work out the molecula formula
- mf=(S1F6)1 ;S 1×1=1 ;F 1×6=6
- mf=SF6
the final answer will therefore be SF6
