The molar mass of I2 : 283.81 g/mol
<h3>Further explanation
</h3>
Given
I2 compound
Required
The molar mass
Solution
Relative atomic mass (Ar) of element : the average atomic mass of its isotopes
Relative molecular weight (M) : The sum of the relative atomic mass of Ar
M AxBy = (x.Ar A + y. Ar B)
So for I2 :
= 2 x Ar I
= 2 x 126.90447 g/mol
= 253.
809 g/mol
= 253.81 g/mol
Im not going to put in a voice recording ( lwk tired to do so ) but here’s a simplified version I did to describe the properties and everything abt the periodic table.If you need me to type out abt the transitioning metals idm since it’s kinda straightforward.Oh and if you need me to include the trends I could if you want
We have to get the formula of methionine.
The formula of methionine is
Methionine is an essential amino acid of human. It is white crystalline solid.
The formula of methionine is C₅H₁₁NO₂S. Methionine contains five carbon atoms, eleven hydrogen atoms, one nitrogen atom, two oxygen atoms and one sulphur atom.
It contains one amino group (-NH₂) and one carboxylic acid group (-COOH). Atoms are depicted in C-atom in grey, H-atom in ivory, O-atom in red, N-atom in blue and S-atom in yellow.
Answer:
0.77 M
Explanation:
Molarity is the concentration of a solution per liter
C= concentration
n= number of moles
V= volume of solution
The formula we will use is C= n/V
C= n/V
C= (1.93 mol NaCl)/(2.5 L of solution)
C= 0.772 mol/L
Since this concentration is given in moles per liters of a solution, this concentration is also the molarity.
C= 0.772 mol/L
*Include two significant digits in final answer*
M= 0.77 M
