Calculate the number of moles of solute in 16.55 mL of 0.1475 M M2Cr3O7
aliina [53]

Number of moles of solute in 16.55 mL of 0.1475 M M2Cr3O7 is 0.00244 moles.

<u>Explanation:</u>

The properties and behavior of many solutions depend not only on the nature of the solute and solvent but also on the concentration of the solute in the solution. Molarity (M) is the concentration of a solution expressed as the number of moles of solute per liter of solution:

Molarity = \frac{moles-solute}{lites-solution},

Here , litres-solution = \frac{16.55}{1000} l = 0.01655l.

⇒ Molarity = \frac{moles-solute}{lites-solution}

⇒ 0.1475 = \frac{moles-solute}{0.01655}

⇒ moles-solute = 0.01655(0.1475)

⇒ moles-solute = 0.00244

Therefore, Number of moles of solute in 16.55 mL of 0.1475 M M2Cr3O7 is 0.00244 moles.
