Question

Ateacher wants to figure out the amount of a solution that is needed for a litration experiment in a class lab. The dass

has 15 students, and each experiment needs 50 ml. of solution
If each student will perform the experiment two times, how many ml of solution will the teacher need for the whole
class?
O 375 ml
750 ml
1500 ml
3000 ml

Answer 1

Answer: A 750

Step-by-step explanation:

The person above is right.

Answer 2

750 ml

Step-by-step explanation:

Given parameters:

Number of students in the class = 15

Volume of solution needed per student = 50ml

Unknown:

Volume of solution needed for the whole class = ?

Solution:

The total volume needed for the class;

= number of students x volume of solution per student

= 15 x 50

= 750ml

The volume of solution needed by the teacher for the whole class is 750mL
