<h3>Answer:</h3>

23 grams Na

<h3>Explanation:</h3>
  • Molarity is the concentration of a solution in moles per liter.
  • Therefore, a solution with a molarity of 3M contains 3 moles of solute in 1 liter of solution, while a solution with 2M contains 2 moles of solute in 1 liter of solution.

Thus, 3 M = 3 moles/liter

         2 M = 2 moles /liter

The difference is 1 mole/Liter

But, 1 mole of sodium 23 g

Therefore;

Mass of sodium = moles × Atomic mass

                           = 1 mole × 23 g/mol

                           = 23 g

Therefore a 3 M solution contains 23 g of sodium more than a 2 M solution.

In metallic bonding, the electrons
Diano4ka-milaya [45]
A metallic bond is a bond between two metals or cations. In metallic bonding, the electrons are shared between the positive ions. The electrons move around between atoms. This is what allows objects with metallic bonds to be malleable and able to conduct electricity.

Xelga [282]

Answer:

A

Explanation:

B is incorrect because asexual reproduction produces an offspring exactly the same as it's parent. Thus the probability does not need to be calculated.

C and D logically do not make sense since B is incorrect and A is correct. I provided the explanation why it is incorrect above.

Thus A is the correct answer.
