Is this right? I am trying to calculate concentration. 10mm (liquid) to 7mm water = 70% @.Sam.
thank you zach
70% of what?
of water
Concentration of water in liquid (percent)
ok well that would be true if adding them together made a total of 10mm of (liquid i guess) but adding them together gives you a total of 17mm not 10
so yuo r fraction should be \[\frac{ 7 }{ 17 }\]
I was given a chart with 10 mm amount of liquid and 7mm amount of water then to figure out the calculation in percentage of concentration of water in liquid. It's for science.
I came out with 70%
ok i might be wrong about the fraction
so you are adding the water into the liquid no?
yes
ok and after we do that the jar/cup will have 17mm of liquid in it right?
by liquid i mean the combination of water and the other liquid before we mixed them
ok so it is 17% ? ?
oh no ! Ooops I meant 7 not 17 way above sorry.
numbers should be 10 and 7 not 17. Sorry : (
well im sorry but i think they are both wrong. i set up a few fractions and got 41.2% water
\[\frac{ 7 }{ 17 }=\frac{ x }{ 100 }\]
cross multiply
why 17?? Where did you get that? Did you add 10 + 7 you mean?
yes let me put it this way...
\[\frac{ water }{ water+liquid }=\frac{x }{ 100% }\]
10mm total amout of liquid to 7mm water = 41.2 %
ok writing it down.
well the total amount of liquid is 17mm and if you picture 7+10 the 7 is going to be less than 50%
I got it I understand ! Thank you so much !!
no problem good luck with science!
I'm calculating the others now. Thanks!
