Question 682778
You have to add water
The amount of acid in liters is:
{{{ .35*100 = 35 }}} liters
---------------------
Let {{{ w }}} = liters of water to be added
{{{ 35 / ( 100 + w ) = .1 }}}
{{{ 35 = .1*( 100 + w ) }}}
{{{ 35 = 10 + .1w }}}
{{{ .1w = 25 }}}
{{{ w = 25/.1 }}}
{{{ w = 250 }}}
You must add 250 liters of water
