2 mol Cl
.100 mol Fe x ------------- = .05 mol Cl
1 mol Fe
Answer:
0.67 g
Explanation:
We know that 1 mole of an element is 6.02 x 10^(23) atoms
Now, arsenic has 5.49 × 10²¹ atoms
Thus;
Number of moles of arsenic = 5.49 × 10²¹ × 1/6.02 x 10^(23) = 9 × 10^(-3) moles
We are told that;
one mole of arsenic = 74.92 g.
Thus, 9 × 10^(-3) moles = 9 × 10^(-3) × 74.92/1 = 0.67428 g ≈ 0.67 g
M (C2H6) = n × M = 4.6 × 30 = 13.8 g.
We are asked to solve the temperature do Potassium Nitrate KNO3 and Sodium Chloride NaCl has the same molar solubility. The answer is 44.5 degrees Celsius. As per the definition of solubility temperature, the solubility increases when the temperature increases where molecules are allowed to move faster at a higher temperature.
Answer:
in an atom or molecule, no two electrons can have the same four electronic quantum numbers. As an orbital can contain a maximum of only two electrons, the two electrons must have opposing spins.
