What is the molarity of a solution that contains 9.63 grams of HCl in 1.5 liters of solution? 1 H 1.01 Hydrogen 17 Cl 35.45 Chlo
madam [21]
Hey there !

Molar mass HCl :

HCl =1.01 + 35.45 => 36.46 g/mol

Number of moles ( solute) :

n = m / mm

n = 9.63 / 36.46

n = 0.2641 moles

Therefore :

M = moles / volume ( L )

M = 0.2641 / 1.5

=> 0.176 M

Provide the correct IUPAC name for Sr(OH)2 - 7H20.
andrey2020 [161]

This question is providing us with the chemical formula of a compound whose name in IUPAC convention is strontium hydroxide heptahydrate according to the following.

<h3>IUPAC nomenclature in hydrates</h3>

In chemistry, the IUPAC allows us to assign specific names for all the chemicals in the world, in order for them to be recognized all around the world and avoid common names which differ from region to region.

Thus, for the compound we are given, we see the presence of a cationic strontium ion and an anionic hydroxide ion, both accompanied by seven molecules of water, which makes it a hydrate.

In such a way, its IUPAC name will be strontium hydroxide heptahydrate, according to the both of the ions and the number of water molecules into it.
