Question

calculate the mass of the following a one mole of C atom the 6.022 into 10 ^ 23 number of H2 molecules

Answer 1

Avogadro's law states that, "equal volumes of all gases, at the same temperature and pressure, have the same number of molecules". For a given mass of an ideal gas, the volume and amount (moles) of the gas are directly proportional if the temperature and pressure are constant. Avogadro's number is the number of particles in a mole of a substance.

Mole is a measurement of an amount of substance; a single mole contains approximately 6.022×1023 units or entities. Ex: A mole of water contains 6.022×1023 H2O molecules
