# Can moles be negative?

Contents

You can have a negative values. It follows the same sorta thinking as or . It just means the change was a negative change and the final value is less than the initial value. So, for example, if there are 4 moles of gas in the reactants (instead of 2), .

## Can you have negative Mols?

mol have a negative 1 (g. mol^ Answer: means the same as g/mol. The negative 1 exponent is just a mathematical way to describe a quantity that is divided by some other one.

## What does a negative KP value mean?

The sign of Kp tells us the direction the PV moves relative to the CO change. The negative value found above means that as the CO goes up, the PV goes down.

## Can you have a molarity over 1?

To make one liter of a 1 molar solution, less than one liter of pure water is usually required. This is because part of the liter of solution is taken up by solute. … This then means that our one mole of solute is being dissolved by less than kg of solvent: thus the molality of a one-molar solution is greater than one.

## Can KP be negative delta N?

In the expression Kp​=Kc​[RT]Δn, the term Δn refers to the difference in the total number of moles of gaseous products and the total number of moles of gaseous reactants. Hence, it can have either positive value or negative value. It can be zero or also an integer or a fraction.

## Can a concentration be negative?

It is not possible for concentration values to be negative.

## Is g mol and g mol 1 the same?

One mole is 6.022 x 1023 particles; this is called Avagadro’s number and is huge. … They all have the same meaning: the mass (in grams) of 1 mole of that substance.

## Can you have a negative equilibrium constant?

1 : The equilibrium constant Kc is a constant which represents how far the reaction will proceed at a given temperature. … When much less than 1 (Kc can never be negative…so when it is close to zero) the reaction hardly occurs at all.

## What does a negative process gain mean?

The process gain is the sensitivity of a process output to a change in the process input. … If, on the other hand, an increase in the process input leads to a decrease in the process output, this is known as a negative gain.

## What is delta N in KP?

Kp is the equilibrium constant and pressures. … So the atmosphere or the pressure. Temperature, just like in all gas laws, needs to be in Kelvin and delta n stands for change in moles of gas. So remember, it’s gas only, and so products minus reactants.

## What is the highest molarity possible?

The maximum molality is 52.8 m. In practical terms, the highest molarity for aqueous solutions is that of the solvent itself, water. One litre of pure water has a mass of 1 kg. Since the molar mass of water is 18.02 g/mol, the molality of pure water is 55.49 mol/kg or 55.49 m.

## How do you calculate normality?

Normality Formula

1. Normality = Number of gram equivalents × [volume of solution in litres]-1
2. Number of gram equivalents = weight of solute × [Equivalent weight of solute]-1
3. N = Weight of Solute (gram) × [Equivalent weight × Volume (L)]
4. N = Molarity × Molar mass × [Equivalent mass]-1
5. N = Molarity × Basicity = Molarity × Acidity.

## Is molarity always less than 1?

The molality of solution is always greater than the molarity. Actually, in molarity we calculate mol per unit L (i.e. volume of solution) while in molality we calculate moles per unit Kg (i.e. mass of solvent).

## Can you have a negative partial pressure?

Partial pressure is never negative. The negative pressure is possible when attractive force exceeds the repulsive forces and in such scenario the molecule will become unstable. There is no such things as negative partial pressure.

## How do you find delta N in KP?

Definition of Kc and Kp

where, Δn = (Total moles of gas on the products side) – (Total moles of gas on the reactants side). Hence ( Delta = (d + c) – (a + b)nonumber ] [The lower case numbers are the exponents] R is the gas constant found in the ideal gas law (0.0821LiterAtmMoleKelvin)
