    Density can be calculated using the following rule:

    density = mass / volume

    This means that:

    volume = mass / density

    volume = 25.5 / 1 = 25.5 ml

    molarity can be calculated using the following rule:

    molarity = number of moles of solute / volume of solution

    This means that:

    number of moles = molarity x volume of solution

    number of moles = 1 x 0.025 liters = 0.025 moles
