Achemistry teacher has a 560-cm length of magnesium ribbon. for a class experiment, each student requires an 8.5-cm length of the ribbon. how many students may receive the required length?

15 students

65 students

48 students

66 students

The correct answer is 65 students.

Explanation:

Step 1: First we must identify the components of the problem to build our equation.

N: number of students

L: Quantity of magnesium tape available

S: Length of tape required by each student

Our equation for determining the number of students who can obtain correct measurements of magnesium tape is:

N=

Step 2: As S=8,5 cm and L=560 cm

Calculation N:

N=

N=65,88

In rounding we are left with N=65, so we say that for 560 cm of magnesium tape, only 65 students will be able to obtain a correct measure to work with.

Have a nice day!

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
