Avagadro's constant states that in every 1 mole of any substance that is in existence, has exactly 6.022 × 10²³ molecules or atoms. That means there are 1.50575 x 10²³ hydrogen molecules in 1 g of hydrogen gas. Therefore 1g of H₂ gas has more molecules than 1 g of methane gas.

Or, R.D = [M1 L3] × [M1 L3]-1 = [M0 L0 T0]. Therefore, the relative density of a substance is dimensionally represented as [M0 L0 T0].

The potential difference is the work done per unit charge. The dimensional formula for potential difference is dimension of work/dimension of charge =dimensions of mass times acceleration times distance/ dimension for charge =M^1L^1T^-2L^1 / A^1T^1 = M^1 L^2 T^-3A^-1 HENCE OPTION "C" IS CORRECT.

Avagadro's constant is equal to 6.023 x 10^23 so we have 1 x (6.023 x 10^23) molecules present which is 6.023 x 10^23. Using the formula number of moles = Mass/Mr 44/44=1 mole of CO2 present.

AVOGADRO'S LAW: At the same temperature and pressure, equal volumes of all gases have the same number of molecules. At STP one mole of any gas occupies a volume of 22.4 L: this is the molar volume.

The internal energy of an ideal gas is therefore directly proportional to the temperature of the gas. In this equation, R is the ideal gas constant in joules per mole kelvin (J/mol-K) and T is the temperature in kelvin.

The following equation relates the standard-state free energy of reaction with the free energy of reaction at any moment in time during a reaction (not necessarily at standard-state conditions): G = free energy at any moment. G = standard-state free energy. R = ideal gas constant = 8.314 J/mol-K.

# of atoms = N * (density) * volume / (Molecular Weight). N is a constant called Avogadro's number and its equal to 6.022*1023 atoms/mole. It can also be molecules per mole. In the above formula density times volume is just the mass.

The ideal gas law is: pV = nRT, where n is the number of moles, and R is universal gas constant. The value of R depends on the units involved, but is usually stated with S.I. units as: R = 8.314 J/mol·K.

Wavelength is defined as the distance between identical points in the adjacent cycles of a waveform. Therefore, the dimensional formula of wavelength would be [M(0) L(1) T(0)] as wavelength is a term that is measured in meters. What is the dimensional formula of an electric field?

The constants a and b are called van der Waals constants. They have positive values and are characteristic of the individual gas. If a gas behaves ideally, both a and b are zero, and van der Waals equations approaches the ideal gas law PV=nRT. The constant a provides a correction for the intermolecular forces.
