Molecular weight (mass):

It is the molecular mass of a substance that can be calculated by sum of atomic weight of atoms that are present in the molecule multiple by the total number of molecule.

In KOH,

Atomic weight of K=39.1

Atomic weight of O=15.9

Atomic weight of H=1

Molecular weight=Atomic weight of K+Atomic weight of O+Atomic weight of H

=56.1 g/mol

So the answer is A that is 56.10 g/mol

The pressure exerted by a gas container depends on

lesya692 [45]

It’s due to the average number of collisions of gas molecules with the container walls per unit time. As such, pressure depends on the amount of gas (in number of molecules), its temperature, and the volume of the container.

Consider the Lewis structure for glycine, the simplest amino acid: (a) What are the approximate bond angles about each of the tw

UkoKoshka [18]

Each carbon is tetrahedrally planar and has three sections, making all bond angles in (a) 120°.(b) hybridization with sp2.(c) If a double bond is present in the compounds, one of the bonds is a sigma connection and the other a pi bond.

<h3>What is an example of an amino acid?</h3>

A basic amino group (NH2), a carboxyl group group (COOH), and an organic Aromatic rings that really is specific to each amino acid make up an amino acid, an organic molecule.

<h3>Which five amino acids are there?</h3>

You must obtain the nine essential amino acids cytochrome c, isoleucine, hcl, lysine, methionine, phenylalanine, alanine, tryptophan, and valine through your food.They are essential for several bodily processes, such as protein biosynthesis, tissue regeneration, and nutrient uptake.

Calculate the mass of 2.00 X 1020 molecules of SO3.

MakcuM [25]

Answer:

0.027g

Explanation:

From Avogadro's hypothesis, 1mole of any substance contains 6.02x10^23 molecules.

From the above, it means that 1mole of SO3 also contains 6.02x10^23 molecules.

1mole of SO3 = 32 + (16x3) = 32 + 48 = 80g

If 1 mole (80g) of SO3 contains 6.02x10^23 molecules,

Then Xg of SO3 will contain 2x10^20 molecules i.e

Xg of SO3 = (80x2x10^20)/6.02x10^23 = 0.027g
