Answer:
0
Step-by-step explanation:
The first solution contributes 0.78*1 = 0.78 L of acid.
The second contributes 0.64*6 = 3.84 L of acid.
There will be 7 L total of the new solution, and 3.84 + 0.78 = 4.62 total L of acid in it. So the new solution has a concentration of 4.62/7 = 0.66, or about 66%.
Answer:
12,922
Step-by-step explanation:
estimate = 16,092 * 803/1,000 = 12,922
The amount of material/ number of pillows made
16/12 = 4/3 = 1 1/3
So the answer lies between integers 1 & 2
