a worker isolates 2.675 g of sif4 after reacting 2.339 g of sio2 with hf. what are the units on theoretical yield , actual yield and percent yield for this problem?

Respuesta :

The theoretical yield would be 4.052 g while the actual yield is 2.675 g

The reaction between SIO2 with HF can be represented by the following equation:

The ratio of SiO2 reacted to SiF4 produced is 1:1.

Theoretically:

mole of 2.339 SiO2 = mass/molar mass

                              = 2.339/60.08

                              = 0.00389 moles

Thus, equivalent mole of SiF4 = 0.00389 moles

Mass of 0.00389 moles of SiF4 = mole x molar mass

                                                  = 0.00389 x 104.0791

                                                   = 4.052 g

Hence, the theoretical yield is 4.052 g while the actual yield is 2.675 g

Both these belongs to reaction yield.
