Question

what Is the empirical formula of titanium sulfide

Weight of crucible is 11.120g

Weight of titanium is 11.120g

Weight of crucible and product is 31.700g

Answer 1

First calculate the Mass of Compound

= Weight of crucible and product - Weight of crucible is 11.120g

=31.700 - 11.120

= 20.580 g

Mass of Sulfur is calculated as follows:

=Mass of Compound - Weight of titanium
= 20.580 – 11.120 = 9.46 g


Now calculate the moles of S and Ti:

9.46 g S x (1 mol / 32.06 g) = 0.295 mol S

11.120 g x (1 mol / 47.87 g) = 0.232 mol Ti

Now calculate the molar ratio of S and Ti as follows:

Mol S= 0.295 / 0.232

= 1.271

Mol Ti= 0.232 / 0.232

= 1.00

convent it into whole number as follows:

1.271*4= 5.0

1.00*4= 4.0

The empirical formula is Ti4S5
