TRUE. (Lorenzo Romano Amadeo Carlo Avogadro) Ideal Gas Law that defined as one in which all collisions between atoms or molecules are perfectly elastic in which there are no intermolecular attractive forces. In such a gas, all the internal energy is the form of kinetic energy and any change in internal energy is accompanied by a change in temperature. That characterized by three state variables: absolute pressure (P) = 1 atm, volume (V) = 22.4 L and absolute temperature (T) = 273 K.
The formula of acetylsalicylic acid is C9H8O4. And the gram formula mass of the molecule is 180 g/mol. So there is 325/180 = 1.8 mol. There is 6.02*10^23 molecules per mol. So the answer is 1.08 * 10^24 molecules.
Answer:
proton number of hydrogen :1
proton number of calcium : 20
number of electrons for fluorine : 9
number of electrons for iodine : 53
number of neutron hydrogen :0
number of neutron iodine : 74
number of neutron gold(Aurum) :118
Explanation:
to get the number of neutron by number of nukleon minus the number of proton..
gold is aurum
the number of nukleon u can get at the periodic table .. by looking at the biggest number.. thats all.. i hope u understanding my explanation :'D hhihi see ya

This question is based on Dalton's Law of Partial Pressure which states that "the total pressure of a system of gas is equal to the sum of the pressure of each individual gas (partial pressure).
Now, Partial Pressure of a gas = (mole fraction) × (total pressure)
⇒ Partial Pressure of Hydrogen =
×
= 0.31 atm
Thus the Partial Pressure of Hydrogen in the container is
0.31 atm.
