# Best answer: How many equivalents are in 5 0 moles of Al3?

Contents

Answer: 5.0 g Al3+ x (1 eq. wt. / 9.0 g) = 0.56 eq. wts.

## How do you find the number of equivalents per mole?

To calculate molar equivalents for each reagent, divide the moles of that reagent by the moles of the limiting reagent: Note that the molar equivalency of sodium benzoate is 1. This is because sodium benzoate is the limiting reagent. Any reagents used in excess will have a molar equivalency greater than one.

## How many equivalents are in 0.40 mole of K+ quizlet?

How many equivalents are in 0.40 mole of K+? 1 eq equals 1 mole, so . 40 eq.

## Are equivalents the same as moles?

By this definition, an equivalent is the number of moles of an ion in a solution, multiplied by the valence of that ion. … (The valency of calcium is 2, so for that ion 1 mole is 2 equivalents.)

## Which has maximum number of equivalent per mole?

2 gram of H2 has the maximum number of moles.

## What is equivalent weight formula?

The formula to calculate the equivalent weight is given as: Equivalent Weight = Molecular weight/ Valency. For example, consider the reaction, H3PO4 → HPO42- + 2H+ The molecular weight of a chemical reaction is 98, and the valency is 2, then the equivalent weight of H3PO4 is.

## How many equivalents are in .40 mole of K+?

Answer. The number of equivalents of the given amount of ion is 0.40 Eq.

## How many equivalents are in 0.036 mole of Ca2+?

5) How many equivalents are in 0.036 mole of Ca2+? Answer: 0.072 equivalents Page Ref: 9.2 Learning Obj.: 9.2 Global Outcomes: G4 Demonstrate the quantitative skills needed to succeed in chemistry.

## How are Mmoles calculated?

Use the molecular formula to find the molar mass; to obtain the number of moles, divide the mass of compound by the molar mass of the compound expressed in grams.

## How many equivalents are in 0.25 moles of H2SO4?

The total is 98.08 grams, so a mole of H2SO4 has a mass of that much. 0.25 moles of H2SO4 would therefore have a mass of a quarter of 98.08, or 24.52 grams.

## What does 3 molar equivalents mean?

A molar equivalent is the ratio of the moles of one compound to the moles of another. … Usually you are relating the moles of the limiting reagent to the moles of other starting materials or reagents used in the reaction.

## Which acid has maximum value of equivalent mass?

sulfuric acid has a molar mass of 98.078(5) g mol−1, and supplies two moles of hydrogen ions per mole of sulfuric acid, so its equivalent weight is 98.078(5) g mol−1/2 eq mol−1 = 49.039(3) g eq−1.
