Answer:
yes, the number of protons makes an atom whatever element it is, and the number of protons cannot be changed, because changing the number of protons would change what element it is. the number of protons in each element is unique.
Explanation:
To solve this, let's assume ideal gas behavior.
PV=nRT
Let's solve for n. Convert units to SI units first.
Pressure = 833 torr(101325 Pa/760 torr) = 111,057.53 Pa
Volume = 250 mL(1 L/1000 mL)(1 m³/1000 L) = 2.5×10⁻⁴ m³
Temperature = 42.4 + 273 = 315.4 K
n = (8,314 J/mol·K)(315.4 K)/(111057.53 Pa)(2.5×10⁻⁴ m³)
n = 94.45 mol
The molar mass of ammonia is 17.031 g/mol.
Mass = 94.45*17.031 = <em>1,608.51 g ammonia</em>

Answer:
I noticed that my skin cells have little tiny holes all over the area I am looking at. I also notice a little bit of dry skin on the skin cell. Not only do I see little holes and dry skin but I also see different types of skin. Rough skin and smooth skin. That is what I see.
