A certain reaction only goes to 75% completion due to the complexity according to the following reaction:

3A + 2B --> 5C

If compound A has a molar mass of 159.7 g/mole and compound C has a molar mass of 57.6 g/mole, how many grams of compound C will be produced from 20.01 grams of compound A and excess compound B?

The answer should be rounded two decimal places. Thanks!

Expert Solution

The reaction:

3A + 2B = 5C

How many grams of compound C will be produced from 20.01 grams of compound A and excess compound B?

Let's use a dimensional analysis for this problem, starting with 20.01g A we first convert them to moles of A using its molar mass (159.7 g/mole), then we convert those moles of A to moles of C using the coefficients in the balanced equation (3A / 5C) and finally we convert those moles of C to grams of C using the molar mass of C (57.6 g/mole):

grams of C = 20.01 g A (1 mole A / 159.7g A) (5 moles C / 3 moles A) (57.6g C / 1 mole C)

grams of C = 12.0285g

grams of C = 12.03g (two decimal places)
