Boyle's Law: P₁V₁ = P₂V₂
So (25 kpa)(0.21) = (2.5 kpa) V₂
(25 kpa × 0.21)/ 2.5 kpa = 2.1
2.1 = V₂

Answer:
to form a metamorphic rock, rocks undergo a change, either caused by high heat, high pressure, or exposure to mineral rich hot liquid, which transforms the existing rock into a new type of rock, changing the minerals’ composition in the process. Any of these three factors, or a combination of them, can lead to a metamorphic rock being formed.
Answer:
24.9 g
Explanation:
Given data
- Volume of the solution: 1.75 L
- Concentration of ammonia: 0.833 M
Step 1: Calculate the moles of ammonia
The concentration of ammonia is 0.833 M, that is, there are 0.833 moles of ammonia (solute) per liter of solution. Then,

Step 2: Calculate the mass of ammonia
The molar mass of ammonia is 17.03 g/mol. The mass corresponding to 1.46 moles of ammonia is:
