What is the percentage purity of sample if 3.92g of mohr's salt react completely with 50 ml N/10 Kmno4 solution

  • chemistry - ,

    Working in N has real advantages over using M but most schools don't teach that now.
    mL x N x milliequivalent weight = g
    50 x 0.1 x 0.392 = ?g
    (?g/3.92)*100 = % purity.
