let x be the no. of molecules in 5.6l
N(A) is Avogadro number=6.022X10236.022X1023
At NTP
,22.4l −−>1mole−−>N(A)
is it ok now

hey dear here is ur answer. Hope it helps you. Mark it as brainliest please.
Molecular mass of HNO3 = 63 Amu
So no. of molecules in 126 Amu = 126 /63 = 2
No. of atoms of Oxygen atoms = 2 x 3 = 6
No. of moles of Oxygen atoms = 6 /6.023 ×10^23 = 9.96 x 10^ -24 moles
Molecular mass of HNO3 = 63 Amu
So no. of molecules in 126 Amu = 126 /63 = 2
No. of atoms of Oxygen atoms = 2 x 3 = 6
No. of moles of Oxygen atoms = 6 /6.023 ×10^23 = 9.96 x 10^ -24 moles

The maximum density of water occurs at 4 °C because, at this temperature two opposing effects are in balance. Explanation: In ice, the water molecules are in a crystal lattice that has a lot of empty space. When the ice melts to liquid water, the structure collapses and the density of the liquid increases.
