For 3 moles of ammonia gas, which of the following is/are trur ? `[N_(A)=6 xx 10^(23)]`

A

It contains 12 `N_(A)` atoms

B

Volume at 1 atm and 273 K is 67.2L

C

Number of molecules is `1.8 xx 10^(24)`

D

Mass % of hydrogen is 17.65

Text Solution

Verified by Experts

The correct Answer is:
A, B, C
PbO, ZnO `rarr` amphoteric oxides
`N_(2)O rarr` neutraoxides
`CO_(2 ),N_(2)O_(3), P_(4)O_(10),P_(4)O_(6)rarr` acidic oxides
BaO = basic oxide
