Answer:
The density of gas is 0.2 Kg / L.
Explanation:
Density:
Density is equal to the mass of substance divided by its volume.
Units:
SI unit of density is Kg/m3.
Other units are given below,
g/cm3, g/mL , kg/L
Formula:
D=m/v
D= density
m=mass
V=volume
Symbol:
The symbol used for density is called rho. It is represented by ρ. However letter D can also be used to represent the density.
Given data:
mass = 0,6 Kg
volume= 3 L
density = ?
Now we will put the values in the formula,
d= m/v
d = 0.6 Kg / 3L
d = 0.2 Kg / L
The density of gas is 0.2 Kg / L.
It could both the 2nd and the 3rd,
because if you add the exponents (2 + 1 + 6 = 9) you don't get 10.
and also each orbital level can and has to carry 2 electrons, and the 2s only has 1 there.
If you were to compare the mass of the products and reactants in a reaction, you would find that the mass of the products is <span>equal to the mass of the reactants.</span>
Answer: Total Number of Atoms is Nine.
We have 3 atoms of (C)carbon, 5 atoms of (H)hydrogen and 2 atoms of (O)oxygen. So total is 3+5+2=10
It means there are 10 atoms in the compound and from the formula we come to know that there are 2 molecules . Therefore 2×10=20 atoms.
C3 means there are 3 atoms of carbon in one molecule
3C means just 3 atoms of carbon
3C3 means there are 3 molecules of carbon with 3 carbon atoms in each molecule. So total atoms is 9.
Hope I helped!
