How many moles of potassium chloride (KCl) are in 4.0 L of a 0.65 M solution? In some cases, using weight is an advantage because mass does not vary with ambient conditions. We multiply the moles by the reciprocal of the given molality (3.0 moles/kg) so that our units appropriately cancel.1. This … land is very good for farming.

Under normal conditions aluminum has a density of 2.70 g/ml. What is the volume of 1.85 g of Aluminum? We call these numbers the atomic weight or the molar mass. Atomic nitrogen has a molar mass of 14 g/mole. How many grams are in 1.5 moles of atomic nitrogen?A mole is how chemists define an amount of substance, useful when dealing with many different molecules reacting at once (i.e. any reaction). So why do chemists use moles, and why do you need a mole calculator? Well, as we said above, it provides a useful metric when dealing with reactions.How many moles of HCl are needed to react with 0.87 moles of Al? Step 1: Be sure that the equation is balanced.

How many moles of the excess reactant remain after the completion of the reaction? answer in mol. A. Which reagent is the limiting reactant when 0.420 mol Al(OH)3 and 0.420 mol H2SO4 are allowed to react? The limiting reactant is the reactant which you do not have enough of!A. Since you are starting with equal moles of the two reactants, you can see from the balanced equation that you need 3 moles of H2SO4 for every 2 moles of Al (OH) 3. So, H2SO4 is the limiting reactant.In one mole of aluminum sulfate, #"Al"_2"(SO"_4")"_3"#, there are 2 moles Al atoms, 3 moles sulfur atoms, and 12 moles O atoms. To determine the number of moles of atoms of each element in 7.00 moles of the compound, multiply the number of moles times 7.00.Explanation of how to find the molar mass of Al2(SO4)3 (Aluminum Sulfate). A few things to consider when finding the molar mass for Al2(SO4)3: - make sure you have the correct chemical formula. - always include the units for molecular weight (grams/mole). - make sure you do the math...How many grams Al2(SO4)3 in 1 mol? We assume you are converting between grams Al2(SO4)3 and mole . You can view more details on each measurement unit: molecular weight of Al2(SO4)3 or mol This compound is also known as Aluminium Sulfate .

Aluminum hydroxide reacts with sulfuric acid as follows:

2 Al(OH)3(s) + 3 H2SO4(aq) → Al2(SO4)3(aq) + 6 H2O(l).

The coefficients in balanced equation point out the ratio of moles of products to moles of reactants.

2 moles of Al(OH)3 react with 3 moles of H2SO4 to produce 1 mole of Al2(SO4)Three and six moles of H2O.

A. Which reagent is the restricting reactant when 0.420 mol Al(OH)3 and zero.420 mol H2SO4 are allowed to react?

The proscribing reactant is the reactant which you should not have sufficient of!

Ratio of Al(OH)3 : H2SO4 = 2 : 3

So, 0.420 mole of Al(OH)3 calls for 3/2 * 0.420 mole of H2SO4 = 0.630 mole of H2SO4. You only have 0.420 mole of H2SO4, so H2SO4 is the restricting reactant.

And

0.420 mole of H2SO4 calls for ⅔ * 0.420 mole of Al(OH)3 = 0.280 mole of Al(OH)3. You have excess moles of Al(OH)3, so Al(OH)Three is in extra

Excess 0.420 – 0.280 =

Ratio of H2SO4 : Al2(SO4)3 = 3 : 1

0.420 mole of H2SO4 will produce ⅓ * 0.420 = 0.14 mole of Al2(SO4)3
