    B. Preparation of a 0,.01 M Zn solution, Primary Standard Individuall Weigh out (to the nearest 0.1 mg) about 0.33 g pure zinc granules and transfer to a 400-mL beaker Dissolve in a minimum amount (-10 mL) of 6 M HCI. Cover the beaker with a watch glass and heat gently to dissolve (hot plate on lowest setting). After the zinc metal is completely dissolved wash the droplets of water on the watch glass with distilled water into the beaker. t, quantitatively transfer the solution to a 500-mL volumetric flask. Let the solution cool to room temperature and then dilute to volume with distilled water. Calculate the molarity of this solution.
    Can someone show me how I would calculate the molarity in this scenario?

    B. Preparation of a 0,.01 M Zn elucidation, Primary Standard Individuall Weigh extinguished (to the direct 0.1 mg) abextinguished 0.33 g guiltless zinc granules and exchange to a 400-mL beaker Dissipate in a restriction total (-10 mL) of 6 M HCI. Cover the beaker with a wait glass and ebullition gently to dissipate (violent extract on last elucidation). After the zinc metal is thoroughly dissipated absterge the droplets of infiltrate on the wait glass with distilled infiltrate into the beaker. t, quantitatively exchange the elucidation to a 500-mL sizetric flask. Let the elucidation remediable to extent region and then enfeeble to size with distilled infiltrate. Rate the molarity of this elucidation.

    Molarity = (mass/molarmass)*(1000/V in mL)

    mass of zinc metal = 0.33 g

    atomicmass of zinc metal = 65.4 g/mol

    size of elucidation = 500 mL

    Molarity = (0.33/65.4)*(1000/500)

                 = 0.01 M
