Answer:
9.6 mL
Step-by-step explanation:
If x is mL of chemical X, and y is mL of chemical Y, then:
x + y = 16
0.05x + 0.09y = 0.074(16)
Solve the system of equations using substitution.
0.05(16 − y) + 0.09y = 0.074(16)
0.8 − 0.05y + 0.09y = 1.184
0.04y = 0.384
y = 9.6
You need 9.6 mL of Y.
Answer:
1/2(p) + 1/5(f-3)
or
1/2(p) + 1/5f - 3/5
The first answer is considered simplified.
