Question 3

Chemistry
1 answer:
harina [27]1 year ago
4 0

Answer: 0.118M

Explanation:

The formula for molarity is: M=\frac{mol solute}{L solution}

First, we need to find the number of moles of NaCl.

2.70gNaCl*\frac{1molNaCl}{58.44gNaCl} =0.05molNaCl

Next, we must convert millimeters to liters. We can do that by dividing the number of mL by 1000.

\frac{425mL}{1000} =0.425L

Now we have our needed data! All we need to do now is plug in our data to the molarity formula.

M=\frac{0.05mol}{0.425L} =0.118M

I hope this helps! Pls mark brainliest!! :)

Which ion in each pair has greater charge density? Explain.<br> (c) Na⁻ or Cl⁻
boyakko [2]

Cl⁻ has a greater charge density than Na⁻.

The amount of electric charge that can build up across a unit length, unit area, or unit volume of a conductor is known as charge density. In other words, it shows the amount of charge that is held in a certain field. It determines how the charge is distributed and can be either positive or negative.

We encounter electric charge density when measuring electric fields from different continuous charge distributions including linear, surface, and volume. We must also take charge density into account when analyzing current electricity. We must first comprehend this concept of density in order to comprehend charge density. The definition of density for a thing is its mass per unit volume.

Size and charge density are inversely correlated, meaning that the smaller the size, the higher the charge density. This implies that Cl has a smaller volume and a higher charge density.
