Question

a) According to the following reaction, how many grams of sulfur dioxide are produced in the complete reaction of 24.1 grams of hydrogen sulfide?

b)

Taking logarithms and antilogarithms is necessary to solve many chemistry problems. For practice, complete the following table, where N is a number.

N	ln N	log N
34.4
	-2.180

Answer 1

a)

2 H2S (g)   + 3 O2 (g)   ----------> 2 H2O (g)   +   2 SO2 (g)

68.16 g                                                                      128.12 g

24.1 g                                                                            ??

mass of SO2 produced = 24.1 x 128.12 / 68.16  

mass of SO2 produced = 45.3 g

b)

N	ln N	log N
34.4	3.538	1.537
0.113	-2.180	0.947
