A chemist wants to mix a 10% acid solution with a 26% acid solution to obtain 16 liters of a 14% acid solution. How much of the 26% solution should she use?

The 26% solution should she use is explained below in detailed explanation.

Step-by-step explanation:

Assumed there be 10 percent of x liters of acid solution

Assumed there be 26 percent of y liters of acid solution

provided Information

A chemist needed to combine a 10 percent acid solution with a 26 percent acid solution to obtain 16 liters of a 14 percent acid solution

So, ( 10 / 100 )*x + ( 26 / 100 )*y = ( 14 / 100 )*16

=> 0.1*x + 0.26*y = 0.14*16

=> 0.1*x + 0.26*y = 2.24 eq 1

x + y = 16 eq 2

Multiply ( 0.1 ) in both side in eq 2

=> 0.1*x + 0.1*y = 0.1*16

=> 0.1*x + 0.1*y = 1.6 eq 3

Subtract eq 3 from eq 1

0.1*x - 0.1*x + 0.26*y - 0.1*y = 2.24 - 1.6

=> 0.16*y = 0.64

=> x = 0.64 / 0.16

=> y = 4

So, 4 liters of 26% solution she should utilized

6x = 48

i hope this . 6 cards each and a total of $48. dvide each side by 6 and you will have your answer.

d. $180

step-by-step explanation:

if the dimensions of the room is 9ft by 12 ft, we have the area of the floor as,

so the area of the floor is 108 square feet, converting that into square yards we get,

the cost of carpet is $15 per square yard, therefore the cost of carpet for 12 square yards is,

hence, the cost of carpet is $180.

assuming the dimensions of the room be,

15 ft by 12 ft

so, the area of the floor of that room is,

we can convert 180 square feet into square yards, we know that,

1 sq ft = 0.111 sq yard

so, 180 square feet is,

so the area of floor is 20 square yards.

now, the cost of carpet is 15 dollars per square yard, therefore the cost of carpet for 20 square yards is,

so, it will cost $300.
