You are about to start a cell biology experiment that requires a number of different chemical reagents. You have an unlimited supply of water and the following materials available in the lab to make your solutions; 500g dry glucose 1500 mL of 40% TRIS-buffer solution 150 mL of 0.3 molar ampicillin 2L of 35% SDS Using precise numerical values (to one decimal place, do NOT include units), describe how you will prepare 150 mL of 8% TRIS-buffer.

The answer is "212.5 ml"

Explanation:

Please find the complete question in the attached file.

In 2 ml of SDS it makes 120 ml of SDS.

To mix x ml of SDS

added water

So we have to add 24ml from SDS and add 96ml water to male 120ml SDS.

1500ml of 40% Tris Buffer solution  

Let us assume we have to mix y ml of 40% Tris buffer solution  

added water  

So we have to add 37.5 ml from 40% Tris Buffer and add 212.5 ml water to male 250 ml 6% Tris Buffer.

output?

explanation:

2fe + 3h2so4 -> fe2(so4)3 + 3h2

it is necessary to balance equations in order to get the proper amount of reactants as well as products in order not to make a miscalculation.

you cannot change the subscripts as that would change the substance itself. for instance, diatomic elements such as h2 only have the subscript two when a gas. another example would be so4, if you were to change the subscript, the element would no longer be sulfate.

we change the coefficients instead as that only changes the number of molecules rather than the substance itself.

hope this !
