Calcium iodide (chemical formula <span>CaI2</span>)
Answer:
this isn't correct answer but the equation is correct by using this methid you can got your answer .
Explanation:
Given - Mass number of atom = 23
Atomic number of atom = 11
As, no. of electrons in an atom is equal to an atomic number of the element.
So, number of electrons = 11
Secondly , number of protons are equal to number of electrons.
so, number of protons = 11
And number of neutrons = mass number - atomic number = 23−11 = 12
so, number of neutrons = 12
So , the atom contains 11 protons, 11 electrons, 12 neutrons.

Answer:
The answer to your question is Pressure = 3.55 atm
Explanation:
Data
R = 0.082 atm L/mol°K
mass = 4.5 g
volume = 2 L
temperature = 35°C
Pressure = ?
Process
1.- Calculate the moles of Methane
molar weight = 12 + 4 = 16 g
16 g of Methane --------------- 1 mol
4.5 g --------------- x
x = (4.5 x 1)/16
x = 0.281 moles
2.- Convert temperature to Kelvin
°K = 273 + 35
= 308
3.- Use the ideal gas law to solve this problem
PV = nRT
- Solve for P
P = nRT / V
- Substitution
P = (0.281)(0.082)(308) / 2
- Simplification
P = 7.097 / 2
- Result
P = 3.55 atm
