Question 426160
Let {{{a}}} = ml of water to be added
{{{ ( .16*26 ) / (26 + a) = .13 }}}
{{{ 4.16 = .13*(26 + a) }}}
{{{ 4.16 = 3.38 + .13a }}}
{{{ .13a = .78 }}}
{{{ a = 6 }}}
6 ml of water should be added
check:
{{{ ( .16*26 ) / (26 + 6) = .13 }}}
{{{ ( .16*26 ) / 32 = .13 }}}
{{{ 4.16 = .13*32 }}}
{{{4.16 = 4.16 }}}
OK
