The mass of an atom comes from
the protons and neutrons that are found in the nucleus. The number of protons
is the atomic number of an element. To find the number of neutrons, subtract
the atomic number from the mass of an atom. So, if an element is 76, the number
of protons AND electrons is also 76.
Answer:
The required volume is 0.84 L
Explanation:
Given,
Mass of O2 gas = 1.20 g
We know,
At STP, molar volume of all gases is 22.4 L
and Molar mass of O2 gas is 32 g
Now,
Number of moles = mass/molar mass
= 1.20/32
= 0.0375
Again,
At STP,
Number of moles = Volume/Molar volume
or, Volume = Number of moles X Molar Volume
or Volume = 0.0375 X 22.4
∴ Volume = 0.84 L
So, the required volume is 0.84 L
Answer:
different elements have different numbers of neutrons.
