+4 / -1
Among the following, choose the ones with equal number of atoms. A. 212 g of Na₂CO₃ [molar mass = 106 g] B. 248 g of Na₂O [molar mass = 62 g] C. 240 g of NaOH [molar mass = 40 g] D. 12 g of H₂ [molar mass = 2 g] E. 220 g of CO₂ [molar mass = 44 g]
A
A, B, and C only
B
A, B, and D only
C
B, C, and D only
D
B, D, and E only
Explanation
Moles calculate karke atoms compare karo; A=2 mol, B=4 mol, D=6 mol etc → equal atoms A, B, D me match hota hai.
