Question

A sample of a substance (containing only C, H, and N) is burned in oxygen. 4.536 g of CO2, 6.632×10-1 g of H2O and 8.835×10-1 g of NO are the sole products of combustion.

What is the empirical formula of the compound?

What was the mass of the initial sample burned?

Organotin compounds play a significant role in diverse industrial applications. They have been used as plastic stabilizers and as pesticides or fungicides. One method used to prepare simple tetraalkylstannanes is the controlled direct reaction of liquid tin(IV) chloride with highly reactive trialkylaluminum compounds, such as liquid triethylaluminum (Al(C2H5)3). 3SnCl4 + 4Al(C2H5)3 --> 3Sn(C2H5)4 + 4AlCl3 In one experiment, 0.220 L of SnCl4 (d = 2.226 g/mL) was treated with 0.471 L of triethylaluminum (Al(C2H5)3); d = 0.835 g/mL).

What is the theoretical yield in this experiment (mass of tetraethylstannane, Sn(C2H5)4)?

If 0.242 L of tetraethylstannane (d = 1.187 g/mL) were actually isolated in this experiment, what was the percent yield?
