Hi there!
• Avogadro's number = 6.023 × 10²³
• No.of molecules in N = 1.806 × 10²² [ Given ]
It's known that :-
Number of molecules = Moles × Avogadro's number
=> 1.806 × 10²² = Mol. × 6.023 × 10²³
=> Mole =
=> Moles = 0.03 mol.
Hence, 0.03 mol. is th' required answer.
~ Hope it helps!
Because if you change the subscripts you can change the whole equestion and can get the wrong balance therefore instead of change subscripts you supports to change the coefficients and coefficients is an among of the rule in balance of chemical equestion.
Answer:
Through Total internal reflection.
such as formation of multiple images.
Explanation:
As the light ray Strikes the mirror surface, the incident ray is refracted away from the normal and critical angle exceeds the normal.
Hence the light ray partially transmitts or refracts and also reflects.
