    Explanation:

    Given dа ta:

    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
