Question

Determine the molarity of 2.50 moles NaCl in 1.00 L solution?

Determine the molarity

Answer 1

2.50 Molar

Explanation:

Molarity is defined as the number of mole of solute per liter of solution,

Mathematically,

`M = (n/V)`

`M = (2.5 / 1.00 )`

`M = 2.5 Molar`

Answer 2

`2.5 \ "M"`

Explanation:

Molarity is expressed through the equation

`"molarity"="moles of solute"/"liters of solution"`

Here, the solute is salt, and the solution has a volume of `1 \ "L"`.

So, the molarity is

`"molarity"=(2.5 \ "mol")/(1 \ "L")=2.5 \ "M"`

Note: We use `1 \ "M"` to represent `1 \ "mol/L"`.
