1. 31
2. 28
3. 3
4. 25

Rethink and reinvent

Using dilution equationm1v1 =m2v2 ; where m1 and m1 are the intiial and final concentration, and v1 and v2 are the initial and final volume.5  × 5 m = 8 l  × m2m2 = 25/8 = 3.125 mtherefore; the resulting molarity is 3.125 m

Where is the rest id like to but i cant if i don't have more info

Can you post list or organisms
