Question 900095
From the view of acid it is
since 100% water has 0% acid
0*x+.6*8=0.5(8+x)
4.8=4+.5x
.8=.5x
.8/.5=x
x=1.6 L
view of water
I changed from percent acid to percent non acid
60% acid means 40 % non acid
50% acid means 50 % non acid
Pure water is 100% non acid as a decimal 100%=1

1*x+0.4*8=0.5(8+x)
1*x+3.2=4+0.5x
1x-0.5x=4-3.2
0.5x=0.8
x=1.6 L Same answer!!!!
check
1*1.6+0.4*8=0.5(8+1.6)
1.6+3.2=0.5(9.6)
4.8=4.8
ok
