Medal
A chemistry experiment requires 14 ml of an acid solution. How many liters of acid should be ordered when 4 classes of 90 students each are going to perform the experiment? (The acid must be ordered by the whole liter.)
? L

Answer 1

is that the whole question?

Answer 2

First change ml \(\to\) L

Answer 3

yes

Answer 4

\[14~\text{mL} \cdot \frac{10^{-3}~\text{L}}{1~\text{mL}}\]

Answer 5

Then just multiply everything together, I believe.

Answer 6

multiply what

Answer 7

Your conversion x # of classes x # of students.

Answer 8

i mean one should do it, there is a 1000 ml in one liter, so one should handle four classes

Answer 9

oh yeah

Answer 10

as 4 classes=> 90*4*14=5040ml
1l = 1000 ml=>
40ml = 40/1000 = 0.4l
total 5040 ml => 5l + 0.4l = 5.4l answer @harz360
