A student wants to determine the empirical formula for titanium sulfide (TixSy). To do so, she reacted titanium with excess sulfur in a crucible, and recorded the following data: Mass of Crucible: 11.120 g Mass of titanium used: 8.820 g Mass of Crucible and product: 31.700 g what is the empirical formula of titanium sulfide based on her experiment?

 The empirical formula is

Explanation:

Mass of Titanium (Ti) = 8.820 g

Mass of  product = (mass of Crucible and product) - mass of crucible = 31.700 g - 11.120 g = 20.58 g

Mass of sulphur (S) = mass of product - mass of titanium = 20.58 g - 8.820 g = 11.76 g

Step 1 : convert given masses into moles

Moles of Ti =

Moles of S=

Step 2 : For the mole ratio, divide each value of moles by the smallest number of moles calculated.

For Ti =

For S =

Thus the ratio of Ti : S = 1: 2

Hence the empirical formula is

the answer would be b i believe

because natural gas is colorless, odorless, and tasteless, distributors add mercaptan (a chemical that smells like sulfur) to give natural gas a distinct unpleasant odor (it smells like rotten eggs). they locate the types of rock that are likely to contain natural gas deposits.
