Find the % by mass of the solute in 129.54 g C6H1206 in 525 g H20.

Chemistry
1 answer:
belka [17]3 years ago
7 0

Answer:

19.79%

Explanation:

mass % = (mass solute / total mass) * 100

total mass = 129.54 + 525 = 654.54

solute = C6H12O6

(129.54/654.54) = .1979

.1979 * 100 = 19.79%

What is the mass of substance that exactly fills a 247.2 mL container? The density of the substance is 0.81 g/mL. Give the answe
matrenka [14]

Answer:

<h2>mass = 200.23 g</h2>

Explanation:

The density of a substance can be found by using the formula

Density =  \frac{mass}{volume}

Since we are finding the mass

<h3>mass = Density × volume</h3>

From the question

Density = 0.81 g/mL

volume = 247.2 mL

Substitute the values into the above formula and solve for the mass

mass = 0.81 × 247.2

= 200.232

We have the final answer as

<h3>mass = 200.23 g to 2 decimal places</h3>

Hope this helps you

The Pauli Exclusion Principle tells us that no two electrons in an atom can have the same four quantum numbers.
Anuta_ua [19.1K]

Answer:

See explanation

Explanation:

We can describe electrons using four sets of quantum numbers;

principal quantum number (n)

orbital quantum number (l)

magnetic quantum number (ml)

spin quantum number (ms)

Since no two electrons in an atom can have the same value for all four quantum numbers according to Pauli exclusion theory, for the orbitals given one possible value for each quantum number is shown below;

For 1s-

n = 1, l= 0, ml = 0, ms= 1/2

For 2s-

n= 2, l =0, ml=0, ms=1/2

For 1s and 2s orbitals, there is only one possible value for ml which is zero.

At the most basic level, in order to produce oxygen and a carbohydrate (comprised of carbon, hydrogen, and oxygen), carbon dioxi
Kaylis [27]

At the most basic level, in order to produce oxygen and a carbohydrate (comprised of carbon, hydrogen, and oxygen), carbon dioxide must react with water as a source of hydrogen.

In order to construct carbohydrate molecules (often glucose) and release oxygen into the atmosphere, photosynthesis utilises carbon dioxide and water. Photosynthesis occurs in organelles called chloroplasts found in eukaryotic autotrophs like plants and algae.

Commonly used notation for photosynthesis is:

6CO_{2} + 6H_{2}O C_{6}H_{12}O_{6} + 6O_{2}

This indicates that the reactants, six carbon dioxide molecules and six water molecules, are transformed into a sugar molecule and six oxygen molecules, the products, by light energy being absorbed by chlorophyll.
