b. 0.30
c. 0.5
d. 0.14"

Answer 1

To find the total grams of tar traveling through the lungs if a person smokes 1 pack of cigarettes, multiply the amount of tar per cigarette by the number of cigarettes in a pack. Therefore, if a person smokes 1 pack of cigarettes, they would inhale 0.14 grams of tar.

Step-by-step explanation:

To find the total grams of tar traveling through the lungs if a person smokes 1 pack of cigarettes, we need to multiply the amount of tar per cigarette by the number of cigarettes in a pack.

1. Convert the milligrams of tar per cigarette to grams by dividing by 1000: 7 mg = 7/1000 = 0.007 g.
2. Multiply the grams of tar per cigarette by the number of cigarettes in a pack: 0.007 g x 20 = 0.14 g.

Therefore, if a person smokes 1 pack of cigarettes, they would inhale 0.14 grams of tar.
