Question

Calculate the molarity of 4g of NaoH in 2 liters of solution

Answer 1

Explanation:

got

1

M

.

Explanation:

Well, first we have to convert

4

g

of sodium hydroxide into moles.

N

a

O

H

has a molar mass of

40

g

/

m

o

l

.

So here, there exists

4

g

40

g

/

m

o

l

=

0.1

m

o

l

Then, molarity is expressed by the equation:

molarity

=

moles of solute

liters of solution

So now, we need to convert

100

m

L

into

L

.

1

L

=

1000

m

L

∴

100

m

L

=

0.1

L

Mark me as brainliest

Since we have now the desired units, we plug them into the equation.

∴

molarity

=

0.1mol

0.1L

=

1

m

o

l

/

L

=

1

M

So, the molarity of the solution will be

1

M

.
