Mass of the steel is 
- density of a substance can be regarded as the ratio of the mass of that substance to that of it's volume.
- Mass of substance can be regarded as the quantitative measure of inertia, it can be simply explained as a fundamental property of all matter
<em> We can express this mathematically as ;</em>
Given :
Density of this steel= 8.1g/cm3
If we make Mass subject of formula,
Then let us substitute the values into the expression
Therefore, mass of the steel is

To find the number of neutrons in an atom you can use and equation
N = Mass no. - Protons
N of chlorine-36 = 36 - 17 = 19
so chlorine-36 has 19 neutrons
hope that helps
Explanation:
Octahedral complexes will be favoured over tetrahedral ones because:
It is more favourable to form six bonds rather than four
The crystal field stabilisation energy is usually greater for octahedral than tetrahedral complexes.
The transition metals Co, Rh, Lr are in group 9 of d block and they have 3d, 4d, and 5d orbitals respectively
Answer:
Answer is A
Explanation:
Now we know that an atom wants to complete its outer shell while keeping electrons in pairs of two now in A there are four electrons which which can be ejected while in B will want to accept 3 electrons to complete its shell as ejecting five will take lot of energy similar case will be for C,D and E which would want to accept 2,1,0 electrons respectively
