It is also an SI derived unit
SI derived unit
The International System of Units (SI) specifies a set of seven base units from which all other SI units of measurement are derived. Each of these other units (SI derived units) is either dimensionless or can be expressed as a product of (positive or negative, but usually integral) powers of one or more of the base units.
How many kilojoules are in a mole?
How many Kilogram-mole make 1 Mole? 1 Mole [mol] = 0.001 Kilogram-mole [kg-mol] – Measurement calculator that can be used to convert Mole to Kilogram-mole, among others. Accordingly, Is kJ kg the same as kW?
How to convert Joule to kJ per mole?

How many units are in a mole?
The mole, abbreviated mol, is an SI unit which measures the number of particles in a specific substance. One mole is equal to 6.02214179×1023 atoms, or other elementary units such as molecules. Moreover, what if you had a mole of moles? A Mole of Moles. It's really just a number—like “dozen” or “billion.”
How do you calculate the number of moles from concentration?
How to Find Moles?
- Definition of Number of Moles. It refers to a huge number that we use to measure atoms. ...
- Molarity Calculation. It refers to the number of moles per litre of solution. Moreover, we express it as M. ...
- Solved Question for You. Mole is approximately equal to which of the following? The correct answer is option A.
How many joules is a kilowatt hour?
A watt is a power unit and is the same as a joule per second (J/s). So if you want to know how many joules is in a kilowatt-hour you multiply by 1000 first to change kW into just W. Next multiply by 3600 which is the number of seconds in an hour. So that is 3.6 million joules for one kW·hr.
How many coulombs are in a bowl of electrons?
Those electrons each have a tiny amount of negative charge, but because there is an entire mole, that charge adds up to 96485 coulombs (the faraday, F ). If we just divide the total charge by the counting amount of electrons which is Avogadro's number, N A = 6.022 × 10 23 we get the following:
How much charge does a proton have?
Therefore, a proton has the same amount of charge which is 1.602 × 10 − 19 C, q p. The other term often used for this tiny amount of charge is elementary charge and has the symbol e.
What is one joule?
By definition, one Joule is the work done by a force of 1 Newton in producing a displacement of 1 metre in an object in the direction of the force. One Newton in turn is that force which produces in an object of 1 kg. Continue Reading. Both Joule and erg are units of work/energy.
How many phospates are in an ATP molecule?
There are 6,022*10^23 molecules in a mole, and there are 3 phospates in one ATP molecule and 2 of them may be splitted off. So the value of 1 ATP molecule is. 40000 J/ (6,022*10^23) = 6,64 * 10^ (-20) joules. OR if we take into account the second macroergic bond (ATP -> AMP)
How many kcal of ATP is in a gram of glucose?
The number 7.3 kCal is not per molecule of ATP but per mol of ATP. The molecular weight of glucose is 180,156 g/mol so in one gram we have 6.023×10²³ /180.156 = 3.33×10²¹ molecules of glucose which means that in energy we have 1.23×10·²¹ kCal/molecule. One mol of ATP is 6.023×10²³ molecules so we have 1.21×10·²¹ kCal/molecule, when balancing energy in this way we have one molecule of ATP per molecule of glucose consumed, but the real number is around 38 molecules of ATP formed per molecule of glucose in the glycolitic and Kreb's cycle concatenation, so from here we see the efficiency of the ca
How much does a triglyceride weigh?
First, let’s replace the term “unit” with mole. The molecular weight of a typical triglyceride, such as triolein, is 885 g/mole. Fat has 9 kcal/g (measured calorimetrically), so we multiply 9 x 885 = 7965 food calories per mole, not just 2500.
Is a joule squared a watt squared?
Since there is no such concept as a watt-squared, the whole joule-watt has no physical significance, and is quite meaningless.
Is a joule a cgs unit?
Both Joule and erg are units of work/energy. The erg is the cgs unit of work/energy and Joule is MKS/ SI unit of the same. By definition, 1 erg is the work done when a force of one dyne produces a displacement of 1 cm in an object in the direction of the force.
