Given the chemical formula, kno3, what is the percent nitrogen in the compound?
a) 13.86%
b) 14.01%
c) 38.36%
d) 47.48%

The answer to your question is letter A

Explanation:

Process

1.- Calculate the molar mass of KNO₃

KNO₃    molecular mass = 39.1 + 14.01 + (3 x 16)

                                        = 39.1 + 14.01 + 48

                                        = 101.11 g

2.- Use a rule of three to find the percent of nitrogen

                            101.11 g of KNO₃     100%

                             14.01 g of N             x

                             x = (14.01 x 100) / 101.11

                             x = 13.86%

answer; i believe that the correct answer is (a) potassium(k)

the answer is true. hope it .
