Question 806914: By weight, liquid A makes up 7.0 percent of solution I and 14.5 percent of solution II. If 3 grams of solution I is mixed with 2 grams of solution II, then liquid A accounts for what percent of the weight of the resulting solution? Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! By weight, liquid A makes up 7.0 percent of solution I and 14.5 percent of solution II.
If 3 grams of solution I is mixed with 2 grams of solution II, then liquid A accounts for what percent of the weight of the resulting solution?
--------
Equation::
liq a + lig a = log a
---------------------------
0.7*3 + 0.145*2 = x(3+2)
-----
Multiply thru by 1000 to get::
700*3 + 145*2 = 5000x
----
2100 + 290 = 5000x
x = 2390/5000
x = 0.478 = 47.8% (% of liquid A in the mixture)
