Answer:
The correct answer is 0.26 M
Explanation:
The initial concentration of NaCl solution (Ci) is 5.0 M. The initial volume of the solution (Vi) is 13 mL. The final volume is the addition of 240 mL to 13 mL (Vf= 13 mL + 240 mL= 253 mL).
In order to calculate the final concentration of the solution (Cf) we can use the following expression:
Ci x Vi= Cf x Vf
This mathematical expression is often used to calculate concentrations in dilution procedures. So, we introduce Ci, Vi an Vf in the expression and we calculate Cf:
Cf= (Ci x Vi)/Vf= (5.0 M x 13 mL)/253 mL= 0.257 M ≅ 0.26 M
Answer:
1707-1778- Carolus LinnaeusHedeveloped the two part naming system fororganisms, using the genus and species,known as scientific naming.1707-1788- Georges-Louis Leclerc,Comte de BuffonIn his writings, he notedthat different regions of the world havedistinct plants and animals, even when theyhave similar environments. This isconsidered to be the first principle ofbiogeography. Buffon also suggested thatspecies may have improved and degeneratedsince creation, and that the Earth is probablymuch older than the 6,000 years widelyaccepted at the time.1769-1832- Georges Cuvier- influencedby the writings of Buffon, Cuvier foundthat layers, or strata, in the Earth's rockeach represent a different period in theEarth's history.
