    Not 100% sure if this is right, but here's what I think it is.

    M = mol/L
    .568 = mol/.0462 L
    = .0262416 mol

    1.396 = mol/.0805 L
    = .112378 mol

    (.0262416 mol + .112378 mol) / (.0462 L + .0805 L) = M

    M = 1.0094077348

    Thanks, the answer's 1.09M

  • Calabasas HS - oops -

    oops!

    (.0262416 mol + .112378 mol) / (.0462 L + .0805 L) = M

    M = 1.0941 and not 1.0094077
