Question

There are 30 students in chemistry class. Each student will be given 0.100g of copper wire for an experiment. 1cm of copper wire weighs 0.0696g. Calculate the length of wire required to cover the experiment for all the students.​

Answer 1

To cover the experiment for all 30 students, approximately 43.10 cm of copper wire is required.

Step-by-step explanation:

To calculate the length of wire required to cover the experiment for all the students, we need to determine the total mass of copper wire needed and then convert it to length.

Given: 30 students, each given 0.100g of copper wire.

1 cm of copper wire weighs 0.0696g.

1. Find the total mass of copper wire: 30 students x 0.100g = 3.0g
2. Determine the length of wire required: 3.0g / 0.0696g = 43.10 cm

The length of wire required to cover the experiment for all the students is approximately 43.10 cm.
