Ms ( mass of solute): 33,6g
mss (mass of solution): 33,6+192g = 225,6g
__________________
C = ms/mss × 100%
C = 33.6/225.6 × 100%
C = 14,89% ≈ 14,9%

If we let x be the number of sample which contains the atoms of carbon (C). Given that according to study, the amount of atoms in carbon sample that are C-13 atoms is 1.07%, the mathematical set-up that would represent the sample is,
= (0.0107)(C)
Answer: the density of the rock
55.91g/ml
Explanation:
The density of the rock after it had being placed in the cylinder of water so the calculation should look like this:
Volume of water substract the mass of the rock:
And that is 142.5 ml - 86.59g =
Answer 55.91 g/ml
So the density of the rock is 55.91g/ml
Answer:
D bohr
Explanation:
bohr model is the diagram in the picture above
<u>One s orbital</u> and <u>one p orbital</u> are the exact types of atomic orbitals of the central atom mix to form hybrid orbitals in CS₂

What is atomic orbital?</h3>
An atomic orbital is a function used in atomic theory and quantum mechanics to explain the position and wave-like behaviour of an electron in an atom. This function can be used to determine the likelihood of discovering any atom's electron in any particular area surrounding the nucleus.
The physical area or space where the electron may be calculated to be present, as predicted by the specific mathematical shape of the orbital, is referred to as an atomic orbital.
The three quantum numbers n, l, and 
which correspond to the electron's energy, angular momentum, and an angular momentum vector component, are used to describe all orbitals in an atom (magnetic quantum number).
