You need to multiply 15 by 2 since each student is doing 2 trials which gives you 30 (you can think of it as 30 students doing it once if that helps you). Then you have to multiply 30 by 50 since the experiment is being done 30 times and each time requires 50mL which equals 1500mL.
Therefore the teacher needs to make 1500mL of solution for the lab.
I hope this helps.
Answer:
my answer is i dont know to be honest this is hard and i have the same question to thanks
Explanation:
Answer:
a). Volume is 30 cm³ and it has a indefinite shape.
Volume of the liquid is measured using a conical flask on the right.
c). Drinking water is a homogeneous mixture though it is a compound. And it has a indefinite shape though it takes up shape of a container.

The concept of Standard electrode potential can be used to accomplish this.
<h3><u>
Standard Reduction Potential</u></h3>
The standard reduction potential belongs to the group of potentials known as standard electrodes or standard cells. The difference in voltage between the cathode and anode is known as the standard cell potential. . All of the standard potentials are determined using 1 M solutions, 1 atm, and 298 K.
The probability of reducing a species is known as its standard reduction potential. It is expressed as a reduction half reaction in writing. Below is an illustration where "A" stands for a generic element and "C" represents the charge.
<u>Standard Reduction Potential:</u>
A⁽⁺+Ce⁻→A
For example, copper's Standard Reduction Potential of Eo=+0.340V) is for this reaction:
Cu²⁺+2e⁻→ Cu
The standard reduction potential and the standard oxidation potential are quite similar. It is the propensity of a species to undergo oxidation under normal circumstances. Additionally, it is written as a half reaction.
