Answer:
one generation to the next via DNA,
Explanation:
Heritable traits are known to be passed from one generation to the next via DNA, a molecule that encodes genetic information. ... Organisms inherit genetic material from their parents in the form of homologous chromosomes, containing a unique combination of DNA sequences that code for genes.
Given :
On a shelf sits a bottle of NaCl solutions with a molar concentration of 2.50 M and a total volume of 300 mL. If 15.0 mL of the solution is added to 985 mL of pure water .
To Find :
The molar concentration of NaCl in the new solution.
Solution :
Molarity M is given by :
Now , 1000 ml of NaCl contains 2.5 moles of NaCl .
So , 15 ml of NaCl contains :
New , volume V = 15 + 985 = 1000 ml = 1 L .
So , putting value of n and V in above equation :
Therefore , the molar concentration of NaCl in the new solution is 0.0375 M .
Hence , this is the required solution .
You need the equation to solve, like the relation between water and carbon dioxide!
Answer:
26.6 g of CaCl₂ are required to make a 4M solution
Explanation:
4 M = Molarity of the solution
This is a type of concentratrion for solutions, that indicates the moles of solute in 1L of solution.
Solution's volume = 60 mL
We need to convert the volume from mL to L → 60 mL . 1L / 1000mL = 0.060L
Molarity = mol / volume (L) → Molarity . volume (L) = mol
4 M . 0.060L = 0.24 mol of solute
Let's convert the moles to mass → Molar mass CaCl₂
0.24 mol . 110.98 g / 1mol = 26.6 g
