Answer:
4.998 × 10²⁴ amu
Explanation:
Given data:
Mass of substance = 8.3 g
Atomic mass unit = ?
Solution:
The mass of one mole of substance is equal the gram per mole of that substance.
atomic mass unit = g/mol
For 8.3 g:
8.3 × 6.022×10²³
4.998 × 10²⁴ amu
The number 6.022 × 10²³ is called Avogadro number.
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.
There's less space, causing the air particles to collide with the walls of the container more frequently. Pressure is that energy caused by molecules striking a surface. Thus, compacting air molecules leads to higher pressure.
Answer:
negitive 5 or -5
Explanation
usally 12-7 = 5 but 7 is first so it you turn 5 to negitive 5
or -5
Dilution of hcl because less no of mole of hcl would be reacting to form zncl2
Answer:
n .= 1 to 4
Explanation:
From the Planck 5
E = hc/lambda
Where lambda is wavelength
E= hf
We will explain the answer here with respect to wavelength. It should be understood that the higher the wavelength of transition, the lower the frequency.
This means that longer transitions will occur at lesser frequencies. From the options the biggest transition is from 2 to 94, while the smallest is from 1 to 4
The transition from 1 to 4 is expected to have the highest energy as it has the shortest wavelength,
Transition from 2 to 94 has the longest wavelength, lowest energy and least frequency
