Question 829840
---
I'm assuming that the solvent is pure water, so the answer is clear.
The answer is the same regardless of the solvent.
---
x = volume of pure water
y = volume of 93% stock solution
---
0x + 93y = 3(x + y)
x + y = 1000
---
put the system of linear equations into standard form:
---
93y = 3x + 3y
x + y = 1000
---
3x - 90y = 0
x + y = 1000
---
copy and paste the above linear system in standard form into this matrix-method solver:

answer:
x = volume of pure water = 967.742 ml
y = volume of 93% stock solution = 32.258 ml
---
check total volume = 967.742 + 32.258 = 1000.000 ml
