Explanation:
Let us assume that volumes is equal to spheres volume of nucleus.
fm = femto meter =
pm = pico meter =
Hence, calculate the volume as follows.
V =
=
= 82.4481 (cubic femtometers)
or, = 82
Now, we will calculate the volume of the atom as follows.
V =
=
= 1436758.4 (cubic picometers)
thus, we can conclude that volume of the nucleus is 82 and volume of the atom is 1436758.4
.

Solubility equilibrium of is given as follows-
Hence, if solubility of is S (M) then-
and
Where species under third bracket represent equilibrium concentrations
So, solubility product of ,
Here,
So,
So,
Hence option (E) is correct
Answer:
17.934 kg of water
Explanation:
If balanced equation is not given; this format can come in handy.
For any alkane of the type : CₙH₂ₙ₊₂ , it's combustion reaction will follow:
2CₙH₂ₙ₊₂ + (3n+1) O₂ → (2n)CO₂ + 2(n+1) H₂O
For butane:
2C₄H₁₀(g) + 13O₂(g) → 8CO₂(g) + 10H₂O(l)
2 moles of butane gives 10 moles of water.
1 mol of any substance has Avogadro number(N) of molecules in it( 6.022 x 10²³)
Mass of 1 mole of any substance is equal to it's molar mass
So, if 2 x N molecules of butane gives 10 x 18 g of water.
Then 1.2 x 10²⁶ molecules will give:
= 17.934 x 10³ g of water
= 17.934 kg of water
