How many Litres of stock HNO3 solution (16.0 M) is required to make 400.0 ml 2.0 M solution

0.6 M

Explanation:

We use the following equation to find the concentration of the diluted solution:

M1V1 = M2V2  

where M1V1 refers to the concentration and volume of the initial solution, respectively,  and M2V2  refers to the concentration and volume of the final solution, respectively.

In this case, we are trying to find the final concentartion, M2:

M2 = M1V1/V2 = (12.0 M * 0.025 L)/ 0.500 L) = 0.6 M

a boiling water reactor does not boil the water. a pressurized water reactor boils the water faster. a pressurized water reactor is heated directly by the core. a pressurized water reactor does not use fission.

the electrical  conductivity  of asolution  of an electrolyte is measured by determining the resistance of thesolution  between two flat or cylindrical electrodes separated by a fixed distance.
