Explanation:
An electron cloud is the region of space that surrounds the nucleus of an atom under the nucleus of the negatively charged sub-atomic particles.
- An atoms is made up of some particles.
- The proton is positively charged and it is located in the nucleus of an atom.
- The neutrons do not carry any charges and occupies the nucleus with protons.
- Electrons are the negatively charged particles outside the nucleus.
- The electron cloud is portion of an atom with greatest probability of finding an electron.

Answer:
The answer to your question is 245 grams
Explanation:
Data
Volume 6.5 L
Molarity = 0.34
mass of CaCl₂ = ?
Process
1.- Calculate the molar mass of CaCl₂
molar mass = (1 x 40) + (2 x 35.5)
= 40 + 71
= 111 g
2.- Convert the grams to moles
111 g of CaCl₂ -------------- 1 mol
x ---------------0.34 mol
x = (0.34 x 111) / 1
x = 37.74 g
3.- Calculate the total mass
37.74 g ------------------ 1 L
x ------------------ 6.5 L
x = (6.5 x 37.74) / 1
x = 245.31
ClBr, two nonmetals
