0.4L = 400ml
Each student effectively adds 10ml of water so 22 students are adding 10ml of water each. Therefore, 22 x 10 = 220ml total in all the containers added by all 22 students
Water left = 400 - 220 = 180

The answer is B.

The quantity of seawater in millimeters that will be left after all 22 students have filled their containers is; 180 mL

How to solve algebra problems?

We are told that the teacher has 0.4 Liters of sea water. Converting that to mL gives;

0.4L = 400ml

We are told that each student adds 10ml of water.

Since there are 22 students each adding 10ml of water each. Then it means that;

Total added by 22 students = 22 * 10 = 220ml

Thus,

Amount of Water left = 400 - 220 = 180 mL
