Question

What is the concentration of a solution which contains 0.446 g of C6H14N4O2 IN 1.250 L of solution? M

Answer 1

Answer:

0.0021 M

Explanation:

Given data:

Mass of C₆H₁₄N₄O₂ = 0.446 g

Volume of solution = 1.250 L

Concentration/Molarity of solution = ?

Solution:

Molarity is used to describe the concentration of solution. It tells how many moles are dissolve in per litter of solution.

Formula:

Molarity = number of moles of solute / L of solution

Now we will calculate the number of moles of solute.

Number of moles = mass/molar mass

Number of moles = 0.446 g/ 174 g/mol

Number of moles = 0.0026 mol

Molarity:

Molarity = 0.0026 mol / 1.250 L

Molarity = 0.0021 M
