How much 3M NaOH (MW=40) can be made from 10.0mL of a 10M solution?

vaieri [72.5K]

Explanation:

The given data is as follows.

$M_{1}$ = 3 M, $V_{1}$ = ?

$M_{2}$ = 10 M, $V_{2}$ = 10.0 ml

Therefore, calculate the volume of given solution as follows.

$M_{1} \times V_{1}$ = $M_{2} \times V_{2}$

Now, putting the given values into the above formula as follows.

$M_{1} \times V_{1}$ = $M_{2} \times V_{2}$

$3 M \times V_{1}$ = $10 M \times 10.0 ml$

$V_{1}$ = 33.3 ml

or, = 0.033 L (as 1 ml = 0.001 L)

Since, molarity of NaOH is given as 3 M and its volume is calculated as 33.3 ml.

Molarity = $\frac{\text{mass of solute}}{\text{molar mass of solute}} \times \frac{1}{\text{volume in L}}$

3 M = $\frac{mass}{40 g/mol \times 0.033 L}$

mass = 3.96 g

Therefore, we can conclude that mass of NaOH is 3.96 g.

Why virus, virions, prions have no place in five kingdom classification

Ainat [17]

Hey, there!!

There is no place for virus, virions, prions in kungdom classification. The reason is they show both living and non living characters, which don't define them whether they are living beings or non living things.

As in 5 kingdoms, the only living organisms are classified.

Kingdom Monera mostly deals with the organism which contains prokaryotic cells.
Kingdom Protista deals with the organism which have eukaryotic cells.
Kingdom Fungi deals with various fungal organism.
Kingdom Plantae deals with various type of plants.
Kingdom Animalia deals with various type of animals.

So, you can see that there is non of the kingdoms which deals with the organism which have similar characteristics like viruses, virions and prions.

Hope it helps...

A drought causes a wildfire which destroys a forest. Which Earth systems interact during this process? (1 point) Select one: a.

Ne4ueva [31]

Answer:

It is the biosphere and hydrosphere that interact when a drought causes a wildfire that destroys a forest. 

Explanation:

Hydrosphere consists of all the water bodies of earth like oceans, seas, rivers, lakes etc. a drought occurs due to scarcity of water which affects the hydrosphere. The scarcity of water causes plants and trees to dry up and become more prone to catching fire

Biosphere includes all the living organisms of the earth. It includes plants, trees, birds, insects, animals etc. A drought dries up a whole area and a small fire that starts up somewhere in a forest would then engulf the whole forest.
