What volume of 1.25 M sodium hydroxide (NaOH) solution can be prepared using 60.0 g of sodium hydroxide? (The mass of one mole o

nataly862011 [7]

Answer:

The answer is

Explanation:

Since the concentration , mass and molar mass of NaOH has been given we use the formula

<h3> $C = \frac{m}{M \times v}$ </h3>

To find the volume

where

C is the concentration

m is the mass

M is the molar mass

v is the volume

Making volume the subject we have

<h3> $v = \frac{m}{C \times M}$ </h3>

From the question

C = 1.25 M

m = 60 g

M = 40.0 g/mol

Substitute the values into the above formula and solve for the volume

We have

<h3> $v = \frac{60}{1.25 \times 40} \\ v = \frac{60}{50} \\ v = \frac{6}{5}$ </h3>

We have the final answer as

<h3>Volume = 1.20 L</h3>

Hope this helps you

Liquid water is about 800 times denser than dry air under standard conditions. Use kinetic molecular theory to explain this diff

Savatey [412]

<em>Kinetic molecular Theory points:</em>

1. Gases molecules are always in random motion.

2. Gases molecule collide with each other and with the walls of container.

3. Gases molecules total volume is negligible as compare to container.

4. There is no attractive forces between the gases particles

5. K.E is directly proportional to absolute temperature.

<em>Why liquid are denser than gases according to K.M.T:</em>

1. As gases are in random motion, so they have weak forces/ no attractive forces (Acc. to KMT) due to this they are apart as compare to liquid which have stronger forces are closer to each other. So volume of gases will be greater. d= m/v

2. K. E of gases are greater than liquid due to this gases move randomly, apart from each another. Due to this their volume will be greater. d= m/v

3. Gases molecules total volume is negligible as compare to container which show that gases molecules have large spaces between them which causes lower in density.

DENIUS [597]

The distance between a carbon atom and an oxygen atom in the co molecule is 0.63

<h3>What is the distance?</h3>

Distance is the measurement of the farness of two objects from each other.
