The chemistry teacher set out a 5 pound jar of salt at the beginning of the day. If each student needs 27.6 grams of salt for an experiment, how many students can perform the experiment before the jar is empty? (hint: 1lb=454grams)
Answer:
82 students
Step-by-step explanation:
In this, the first thing you should do is convert the five pounds to grams, which is 2270 grams. Now, all you need to divide 2270 by 27.6 to get the number of students because each student uses 27.6 grams and there 2270 grams being set each day. This gives you 82.2463768116 technically, but you should just round up, and that gives you 82 students. I hope this helped :D
Approximately 82 students can perform the experiment before the 5-pound jar of salt is empty.
In order to determine how many students can perform the experiment with the given jar of salt, we need to convert the jar's weight from pounds to grams, and then divide that by the amount of salt each student requires.
1. Given data: 1 pound = 454 grams (conversion factor).
2. The jar's weight is 5 pounds, so we multiply 5 by 454 to find the total grams of salt initially present in the jar:
5 pounds × 454 grams/pound = 2270 grams.
3. Each student needs 27.6 grams of salt for the experiment.
4. To find the number of students that can perform the experiment, we divide the total grams of salt by the grams per student:
Number of students = Total grams of salt / Grams per student.
Number of students = 2270 grams / 27.6 grams/student ≈ 82.42 students.
5. Since we can't have a fraction of a student, we round down to the nearest whole student (as we can't have a fraction of a student), yielding about 82 students.
6. However, we should also consider that after 82 students, there will be some salt left, but not enough for a complete experiment. Therefore, let's find out how much salt would be left after 82 students.
7. Salt used by 82 students = 82 students × 27.6 grams/student = 2263.2 grams.
8. Salt left in the jar = Total initial salt - Salt used by 82 students = 2270 grams - 2263.2 grams = 6.8 grams.
9. Since the remaining 6.8 grams is not sufficient for another complete experiment, we can conclude that approximately 82 students can perform the experiment before the jar is empty.
In conclusion, about 82 students can perform the experiment using the given 5-pound jar of salt.

Aldo wants to pour 26.26 grams of salt into a container. So far, he has poured 22.27 grams. How much more salt should aldo pour?
Answer: 3.99 grams
Step-by-step explanation:
You can easily break this up into 26-22 and .26-.27. 26-22 is equal to 4, while .26-.27 is equal to negative .1. 4 minus .1 is equal to 3.99, so we need to add 3.99 grams more salt to the container.
