The number of atoms present in 2.5moles of a triatomic gas is equivalent to [1mole = \(6.02\times 10^{23}\)]

Answer Details

One mole of a substance contains a specific number of particles, which is called Avogadro's number, represented by \(6.02\times 10^{23}\) particles per mole. Therefore, to find the number of particles present in 2.5 moles of a substance, we can simply multiply Avogadro's number by 2.5: Number of particles = 2.5 moles x Avogadro's number Number of particles = 2.5 x \(6.02\times 10^{23}\) Number of particles = \(1.505\times 10^{24}\) So the answer is option (C) \(1.5\times 10^{24}\), which represents the number of atoms present in 2.5 moles of the triatomic gas.
