If gasp cigarettes have 5 mg tar and 0.4 mg nicotine per cigarette and there are 20 cigarettes per pack, how many cigarettes wou
Akimi4 [234]

Answer:

a) 1133.98 ≈ 1134 packs

b) 125 packs

Step-by-step explanation:

Given:

Tar present in 1 cigarette = 5 mg

Nicotine present in 1 cigarette = 0.4 mg

Number of cigarettes in 1 pack = 20

thus,

Tar present in 1 pack of cigarette = 5 × 20 = 100 mg

Nicotine present in 1 pack of cigarette = 0.4 × 20 = 8 mg

now,

1 oz = 28349.5 mg

thus,

for 4 oz = 4 × 28349.5 mg = 113398 mg

Therefore,

Number of packs required for 4 oz ( 113398 mg ) tar

= \frac{113398}{100}

= 1133.98 packs ≈ 1134

also,

Number of packs required for 1 g (1000 mg) nicotine

= \frac{1000}{8}

= 125 packs
