The question is incomplete, here is the complete question:
Calculate the volume in liters of a 0.13 M potassium dichromate solution that contains 200. g of potassium dichromate . Round your answer to 2 significant digits.
<u>Answer:</u> The volume of solution is 5.2 L
<u>Explanation:</u>
To calculate the volume of solution, we use the equation used to calculate the molarity of solution:

We are given:
Molarity of solution = 0.13 M
Given mass of potassium dichromate = 200. g
Molar mass of potassium dichromate = 294.15 g/mol
Putting values in above equation, we get:

Hence, the volume of solution is 5.2 L
Number of moles of HCl =

=

= 0.763 mole
From balanced equation:
4 moles of HCl give 2 moles Cl2
0.763 mole HCl give ?? mole Cl2
by cross multiplication :
= 0.38 mole Cl2
mass of Cl2 = moles x molar mass = 0.38 x 70.9 = 27 g
Answer: Solids and liquids don't suddenly change their volumes.
But gases do...they expand to fill whatever container you
put them in.
Michael's mystery substance is in the gaseous phase.
Explanation:
Answer: The rock formed from cooling lava.
Explanation:Extrusive igneous rocks, also known as volcanic rocks, are formed at the crust's surface as a result of the partial melting of rocks within the mantle and crust.
A bond is a force of attraction between atoms as a result of transfer or sharing of electrons. Covalent bond is a bond between non metal atoms that results from sharing of electrons between the atoms. A single atom is formed when atoms share a pair of electron during formation of covalent bonds. Therefore, single covalent bonds exist in a molecule of carbon tetrachloride ( 4 single covalent bonds )
