I believe the correct answer from the choices listed above is the last option. The mass of the methanol sample would be 64 grams. It was calculated by multiplying the number of moles to the molar mass of methanol. Hope this answers the question. Have a nice day.

Answer:

64

Explanation:

Mole of a compound = mass of a compound / molar mass of a compound

Mass of a compound = mole of a compound x molar mass of a compound

Given,

Mole of methanol = 2 mol

Molar mass of methanol = 32 g/mol

Mass of methanol = Mole of methanol x Molar mass of methanol  

                               = 2 mol x 32 g/mol = 64 g

Therefore, the mass, in grams, of the sample = 64

NH4OH is a chemical formula.  It has 5 H atoms per each molecule.  NH<em><u>4</u></em>O<em><u>H</u></em>

<em><u /></em>

5NH4OH means 5 molecules (or moles) of NH4OH.  But the question asks per chemical formula, so 5 is correct,

There would be 5x4 or 20 atoms of H is 5 molecules of NH4OH.

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.
