The answer is: 500g
We are asked to find the theoretical yield of a reaction, and we are given the following information:
[tex]ActualYield=50g\\PercentYield=10(Percent)[/tex]
In order to find the the theoretical yield we must use the following formula:
[tex]PercentYield=\frac{ActualYield}{TheoreticalYield}*100(Percent)[/tex]
We have to convert the percents to real numbers before the calculations. We can do it dividing the percent value into 100, so:
[tex]10(Percent)=\frac{10}{100}=0.1[/tex]
[tex]100(Percent)=\frac{100}{100}=1[/tex]
Therefore,
[tex]TheoreticalYield=\frac{ActualYield}{PercentYield}\\\\TheoreticalYield=\frac{50g}{0.1}=500g[/tex]
Have a nice day!
