Question 1
1 / -0

If Avogadro’s number is 6 × 10²³ then the number of protons, neutrons and electrons in 14 g of ₆C¹⁴ are respectively

A
36 × 10²³ 48 × 10²³, 36 × 10²³

B
36 × 10²³, 36 × 10²³, 36 × 10²¹

C
48 × 10²³, 36 × 10²³, 48 × 10²¹

D
48 × 10²³, 48 × 10²³, 36 × 10²¹

Solution

Since the number of protons, neutrons and electrons in an atom of 6^C¹⁴ are 6, 8 and 6 respectively. As 14 gm of 6^C¹⁴contains 6 × 10²³ atoms, therefore the numbers of protons, neutrons and electrons in 14 gm of 6^C¹⁴ are 6 × 6 × 10²³= 36 × 10²³
