Question

You began with 22 grams of nitrogen, and produced 19 grams of ammonia, `NH_3`, According to the the mass calculations, you should be able to produce 26 grams of ammonia. What is the percent yield? `N_2 + 3H_2 ->2NH_3`

Answer 1

The percent yield is 73 %.

The formula for percent yield is

`color(blue)(bar(ul(|color(white)(a/a) "Percent yield" = "actual yield"/"theoretical yield" × 100 %color(white)(a/a)|)))" "`

∴ `"Percent yield" = (19 color(red)(cancel(color(black)("g"))))/(26 color(red)(cancel(color(black)("g")))) × 100 % = 73 %`
