Answer:
The percent yield of a reaction is 85.04%
Explanation:
Mass of = 47.5g
Molar mass of = 232 g/mole
Molar mass of = 18 g/mole
Volume of water obtained from the reaction , V= 9.40mL
Mass of water = m = Experimental yield of water
Density of water = d = 1.00 g/mL
Moles of tungsten(VI) oxide =
According to recation 1 mole of tungsten(VI) oxide gives 3 moles of water, then 0.2047 moles of tungsten(VI) oxide will give:
Mass of 0.6141 moles of water:
0.6141 mol × 18 g/mol = 11.054 g
To calculate the percentage yield of reaction , we use the equation:
% yield = {
The percent yield of a reaction is 85.04%
