The answer is B. two chlorine atoms.
The chemical formula of the compound is BaCl2~
Answer:
• Molecular mass of Iron (III) tetraoxide
[ molar masses: Fe → 56, O → 16 ]
Answer:
I believe it's D
Explanation:
they both are worked a lot and it makes the most sense.
The molarity of a solution in which 55. 49 g of calcium chloride is dissolved in enough water to make 500. ml of solution is 1M.
<h3>What is molarity? </h3>
It is defined as number of moles of solute divided by volume of solution.
Given,
Mass of CaCl2 =55.49g
Molar mass of CaCl2 =40+35+35=110g
Mole= given mass/ molar mass
= 55.49/110=0.50mol.
Now, putting all values we get the molarity
Molarity =0.5×1000/500=1M
Thus, the molarity of given solution is 1M.
