The resulting solution is unsaturated.

An unsaturated solution is one in which the amount of solute can be increased. We know that the solution is unsaturated because there is no salt at the bottom of the solution and no means were required to increase the salt's solubility such as increasing temperature or stirring. Once the solution becomes saturated, additional salt will only deposit at the bottom unless changes in conditions are made.

How many moles are equal to 12.65 grams of Al2(SO4)3?
____ [38]

Answer:

0.03697 mol Al₂(SO₄)₃

General Formulas and Concepts:

<u>Chemistry - Atomic Structure</u>

  • Reading a Periodic Table
  • Using Dimensional Analysis

Explanation:

<u>Step 1: Define</u>

12.65 g Al₂(SO₄)₃

<u>Step 2: Identify Conversions</u>

Molar Mass of Al - 26.98 g/mol

Molar Mass of S - 32.07 g/mol

Molar Mass of O - 16.00 g/mol

Molar Mass of Al₂(SO₄)₃ - 2(26.98) + 3(32.07) + 12(16.00) = 342.17 g/mol

<u>Step 3: Convert</u>

<u />12.65 \ g \ Al_2(SO_4)_3(\frac{1 \ mol \ Al_2(SO_4)_3}{342.17 \ g \ Al_2(SO_4)_3} ) = 0.03697 mol Al₂(SO₄)₃

<u>Step 4: Check</u>

<em>We are given 4 sig figs. Follow sig fig rules and round.</em>

We already have 4 sig figs in the final answer, so no need to round.

What is the degree of unsaturation for a compound with the molecular formula c6h6?
Nesterboy [21]

Answer:

The degree of unsaturation for a compound with molecular formula C₆H₆ is 4.

Explanation:

The degree of unsaturation is calculated through the following formula:

2n + 2 - H / 2

n = Total number of hydrogen in given compound

There are six hydrogen in given compound, now we will calculate the degree of unsaturation by putting the value of n= 6

(2(6) + 2 - 6 )/ 2

(12+ 2 - 6) / 2

(14 - 6) /2

8 / 2 = 4

The degree of unsaturation for a compound with molecular formula C₆H₆ is 4.

The given compound is benzene and degree of unsaturation is 4. Three double bond and one ring.

24g copper is submerged in water in a graduated cylinder, the total volume increases bu 2.7ml what is the density of copper
Brilliant_brown [7]

Answer:

<h2>8.89 g/mL</h2>

Explanation:

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

density =  \frac{mass}{volume} \\

From the question we have

density =  \frac{24}{2.7}  \\  = 8.88888...

We have the final answer as

<h3>8.89 g/mL</h3>

Hope this helps you
