Answer:
1.58 M
Explanation:
is 1.66 m concentration.
Which means that 1.66 moles of are present in 1 kg of the solvent, water.
Mass of water = 1 kg = 1000 g
Moles of = 1.66 moles
Molar mass of = 98.079 g/mol
The formula for the calculation of moles is shown below:
Thus,
Total mass = 1000 g + 162.81114 g = 1162.81114 g
Density = 1.104 g/mL
Volume of the solution = Mass / Density = 1162.81114 / 1.104 mL = 1053.27 mL = 1.05327 L
Considering:-
<u>Molarity = moles/ Volume of solution = 1.66 / 1.05327 M = 1.58 M
</u>
In mineralogy and crystallography, a crystal structure<span> is a unique </span>arrangement of atoms<span> in a </span>crystal. Atomic arrangement of atoms in this kind of structure usually very symmetrical and highly ordered. Causing the component within the structure is so strong and hard to break. <span>A </span>crystal structure<span> is composed of a unit cell, a set of </span>atoms arranged<span> in a particular way; which is periodically repeated in three dimensions on a lattice. </span>Crystal structure would be commonly found in solid compounds.
Answer:
A. = 143
B. = 8
C. =32
Explanation:
Number of neutron = mass number - atomic number
P(total)=P1+P2+P3+...
P(total)=P(N2)+P(others)+P(O2)
100kPa=78kPa+1kPa+P(O2)
P(O2)=100-79=21kPa
Answer:
C . causes environmental acidification due to production of sulfuric acid.
