How many molecules are present in 1.30 moles of CCl₄? A)2.00 10²⁵ B)7.83 10²³ C)1.30 10²³ D)7.83 10²⁴

Question

Quizplus · Accepted Answer

To calculate the number of molecules present in a given number of moles of a substance, we use Avogadro's number, which is 6.022 x 10^23 molecules per mole. Therefore, the number of molecules in 1.30 moles of CCl₄ is: 1.30 moles x 6.022 x 10^23 molecules per mole = 7.83 x 10^23 molecules The correct answer is therefore B, which matches this value. The other answer choices are either too small (A and C) or too large (D).
