What is the molarity of 5 g of NaOH in 750 mL of solution?
THERE ARE
Pl

0.167M

Explanation:

First, let us calculate the number of mole of NaOH present in 5g. This is illustrated below:

Molar Mass of NaOH = 23 + 16 + 1 = 40g/mol

Mass of NaOH from the question = 5g

Number of mole = Mass /Molar Mass

Number of mole of NaOH = 5/40

Number of mole of NaOH = 0.125mol

Now, we can easily find the molarity of the solution as follows:

Mole = O.125mole

Volume = 750 mL = 750/1000 = 0.75L

Molarity =?

Molarity = mole /Volume

Molarity = O.125mole/0.75L

Molarity = 0.167M

Therefore, the molarity of the solution is 0.167M

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.

the answer is b. dilution
