Alaboratory technician needs to make a 36-liter batch of a 40% acid solution. how can the laboratory technician combine a batch of an acid solution that is pure acid with another that is 10% to get the desired concentration?

how many liters of pure acid solution?

how many liters of the 10% acid solution?

The values of x and y are x = 12 and y = 24.

Step-by-step explanation:

Let x liter pure acid and y liter 10% acidic solution.  

------------------(1)

-----------------(2)

solve for x and y  

From eq(1), we get that

Put in eq(2), we get

x=36-24=12

Hence, the values of x and y are x = 12 and y = 24.

answer: it is 1: 47 pm

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

hope this : )
