34. Which of the following pairs contain equal number ofatoms?(1) 11.2

1.	34. Which of the following pairs contain equal number ofatoms?(1) 11.2 cc of the N2 and 0.015 g of nitric oxide(2) 22.4 litres ofnitrous oxide and 22.4 litres of nitricoxide3li mole of HCl and and 0.5 mil mole of H2S4) 1 mole or H,O, and 1 mole of N,O
Answer» 1) 11.2 cc = 11.2 cm³ = 11.2 ml so, no..of moles of N2 = 11.2 ×10-³ L/22.4 L = 0.0005 moles in 0.015g of nitric oxide ( M = 30g) , the no. of moles will be 0.015/30 = 0.0005 moles since both the compounds have same moles so , option 1 is correct...

Answer»

1) 11.2 cc = 11.2 cm³ = 11.2 ml

so, no..of moles of N2 = 11.2 ×10-³ L/22.4 L = 0.0005 moles

in 0.015g of nitric oxide ( M = 30g) , the no. of moles will be 0.015/30 = 0.0005 moles since both the compounds have same moles

so , option 1 is correct...
