You can find further information regarding each unit of measurement: the molecular weight of Copper(I) Oxide or grams. The molecular formula for Copper(I) Oxide is Cu2O. The SI base unit for the amount of substance is the mole. One mole translates to 1 mole of Copper(I) Oxide, equating to 143.0914 grams.
The neutralization reaction that occurs between potassium hydroxide and sulfuric acid can be represented as follows
2KOH + H2SO4 ---> K2SO4 + 2H2O
The quantity of moles of KOH is calculated using (43.74 x 0.500)/ 1000 = 0.02187 moles
Given that the stoichiometric ratio of KOH to H2SO4 is 2:1, the moles of H2SO4 can be determined as 0.02187/2 = 0.01094 moles
To find the concentration (molarity), use the formula (0.01094/50) x 1000 = 0.2188M
The molecular formula is C2H6O2
Attached is the solution:
Initially, convert the mass into moles.
Then, divide each mole by the smallest amount to identify the number of atoms in the empirical formula.
Next, calculate the empirical formula mass.
Then, determine the molecular formula by dividing the molar mass by the empirical formula mass.
Finally, multiply the empirical formula by the obtained answer to arrive at the molecular formula of the compound.
1) 1 nm = 0.001 µm; which indicates that one nanometer equals 0.001 (10⁻³) micrometer.
d(H) = 10 nm; the diameter of a hydrogen atom.
d(H) = 10 nm · 0.001 µm/nm.
d(H) = 0.01 µm = 10⁻² µm.
2) 1 nm = 10⁻⁹ m; illustrating that one meter is equivalent to 0.000000001 (10⁻⁹) meter.
d(H) = 10 nm.
d(H) = 10 nm · 10⁻⁹ m/nm.
d(H) = 0.00000001 m = 10⁻⁸ m.
3) 1 nm = 10⁻⁶ mm; showing that a nanometer corresponds to 0.000001 (10⁻⁶) millimeter.
d(H) = 10 nm · 10⁻⁶ mm/nm.
d(H) = 0.00001 mm = 10⁻⁵ mm.
