Question

In a chemistry class, 6 liters of a 4% silver iodide must be mixed with a 10% solution to get a 6% solution. How many liters of the 10% are needed?

Answer 1

.04(6L)+.1(x)=.06(6+x)
4(6)+10x=6(6+x)
24+10x=36+6x
4x=12
x=3 liters

Answer 2

ur quick. i just finished he is right

Answer 3

thanks

Answer 4

you are great!!!

Answer 5

what he did was compare the percentage of acid
04(6L)+.1x is the amount of acid so if we divide that by the amount of solution:
6+x we get the percentage which should b equal to 6% so:
(.04(6)+.1x)/(6+x)=.06

Answer 6

You make it sound so easy, thanks
