Now dilute 10.0 ml of the 0.50 m nacl by adding distilled water until 100 ml of solution are produced.

do the 100 ml of diluted nacl have more, less, or the same quantity of nacl as the original 10.0 ml of 0.50 m nacl?

more
less
the same

the same

Explanation:

According to the dilution law,

where,

= molarity of stock solution = 0.50 M

= volume of stock solution = 10 ml= 0.01 L  (1L=1000ml)

= molarity of resulting solution = ? M

= volume of resulting solution = 100 ml = 0.1 L

Therefore, the Molarity of resulting solution is 0.05 M

1. when volume is 10 ml or 0.01L   (1L=1000ml)

moles of

2. when volume is 100 ml or 0.1L   (1L=1000ml)

moles of

Thus they contain same amount of .

it is the minimum amount of material needed to sustain a fission reaction.

critical mass is the minimum amount of fissionable material that must be assembled for a sustained fission reaction to take place. although two to three neutrons are produced for every fission, not all of these neutrons are available for continuing the fission reaction. if the conditions are such that the neutrons are lost at a faster rate than they are formed by fission, the chain reaction will not be self-sustaining.   at the point where the chain reaction can become self-sustaining, this is referred to as critical mass.
