Question

Suppose you had 4.0 moles of solute dissolved into 2.0 liters of solution. what is the molarity

Answer 1

Answer:

M

=

2.0

m

o

l

L

−

1

Explanation:

The molarity,

M

of this solution can be calculated by a formula which is;

M

=

n

V

where;

M

= Molarity of solution

n

=Number of moles of solute

V

= Volume of solution in Litre

Given,

n

=

4.0

moles and

V

=

2.0

L, so we have enough information to calculate the molarity of the solution;

M

=

n

V

M

=

4.0

or

M

=

because

L
