Answer: 22.4L
Gas at STP means gas at standard temperature and pressure of one mole of an ideal gas
Ideal gas Law PV=nRT
Standard pressure is 1atm or 22.4L
Standard temperature is 273.15K

Answer:The rock forms large crystals
Explanation:
0.24J/g*degC * 4.37g * 2.5degC = 2.622J
The 2.5 degC is the difference between 25 and 27.5 deg C.
Hello Mate!Well, there are
many definitions and descriptions of isolated systems, and
here are some of them:
1.
It can be a physical system which is located very very far from all other systems, so there is absolutely no interaction between them, thus making it isolated.
2.
It can be a thermodynamic system with rigid walls, which prevents mass and energy to pass through.
I Hope my answer has come to your Help. Thank you for posting your question here in
We hope to answer more of your questions and inquiries soon.
Have a nice day ahead! :)
Answer:
2.0 M
Explanation:
Step 1: Given data
- Mass of NaCl (solute): 2.93 g
- Volume of the solution: 0.025 L
Step 2: Calculate the moles corresponding to 2.93 g of NaCl
The molar mass of NaCl is 58.44 g/mol.
2.93 g × 1 mol/58.44 g = 0.0501 mol
Step 3: Calculate the molarity of the solution
Molarity is equal to the moles of solute divided by the liters of solution.
M = 0.0501 mol/0.025 L = 2.0 M
