Question

3. Nicotine, the addictive drug in cigarettes, contains 74.0% carbon, 8.6% hydrogen,

and 17.3% nitrogen. What mass of each element can be recovered from a 55.0-
gram sample of nicotine?

Answer 1

To determine the mass of each element in a 55.0-gram sample of nicotine, multiply the given percentage composition by the total sample mass: 40.7 g of carbon, 4.73 g of hydrogen, and 9.52 g of nitrogen can be recovered.

Step-by-step explanation:

The student asked how to find the mass of each element (carbon, hydrogen, and nitrogen) in a 55.0-gram sample of nicotine, given its percent composition. To find the masses, we multiply the percentage of each element by the total mass of the nicotine sample.

Mass of carbon = 74.0% of 55.0 g = 0.740 × 55.0 g = 40.7 g

Mass of hydrogen = 8.6% of 55.0 g = 0.086 × 55.0 g = 4.73 g

Mass of nitrogen = 17.3% of 55.0 g = 0.173 × 55.0 g = 9.52 g

Therefore, from a 55.0-gram sample of nicotine, 40.7 grams of carbon, 4.73 grams of hydrogen, and 9.52 grams of nitrogen can be recovered.

Answer 2

the mass of each element can be recovered from is 162.23 grams

Step-by-step explanation:

the mass really depends on the volume. If there is 74.0% carbon, 8.6% hydrogen and 17.3% nitrogen then you first cross out the 0 and 3 which leaves you with 17% and 74%. Then all you have to do is multiply 17% and 74% and then divided it by 8.6%.
