**Visible confusion** no problem
the answer to your question is
M1V1=M2V2
V2=750-150=600 ml
0.75M*750 ml = M2*600
M2=0.75*750/600 ≈ 9.38 M
Answer:

Explanation:
For this question, we must use Dalton's Law of Partial Pressures:
The partial pressure of a gas in a mixture of gases equals its mole fraction times the total pressure:

Data:
χ = 0.7808

Calculation:

Butter is made of milk, which is made of several things. To do calculations with bomb calorimetry, we often need the number of moles of the substance that we’re using. Since we can’t just say “moles of milk”, it’s not on a table.
