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>
Answer:
all electrons of the atom
A mole of one element contains Same number of atoms as a mole of another element.
The atomic mass of an element, that is found on the periodic table, may be used to determine the amount of moles in a system. Typically, this mass represents the average of the element's abundant forms found on earth. The mass of an element is given as the average of all of its earthly isotopes. The molar mass of a material is the weight of a mole of that substance. In chemistry, the molar mass is frequently used in converting grams of a chemical to moles. The periodic table lists an element's molar mass, which is its atomic weight in grams per mole (g/mol).
The average mass of an element's atoms expressed in atomic mass units is known as its atomic mass (amu, also known as daltons, D). The weight of the each isotope is combined by its abundance to get the atomic mass, which is a weighted average of all the isotopes of that element.

Answer:
N2 (but the 2 is a subscript) i think
Explanation:
i looked it up
Answer:
2H2 + O2 -----> 2H2O
Not sure about the second question though.
