Answer:
4.332 millimoles of NaOH
Explanation:
Molarity (M) = moles per liter (mole/L); liters x moles/liter = moles
0.04332 L x 0.1 mole/liter = 0.004332 moles of NaOH (4.332 millimoles)
millimoles / milliliters = moles/liter = molarity (M).
4.332 millimoles / 50 milliliters = 0.08664 M HCl
In the Volumetric titration at the end point, moles of NaOH = moles of HCl
NaOH + HCl --> H2O + NaCl
Answer:
Difference between Homogeneous mixture and Heterogeneous Mixture are as follows:
- A mixture or sample that is consist of uniform composition and properties is called a homogeneous mixture while a mixture or sample that is consist of different composition and properties is called a heterogeneous mixture.
- Homogenous mixture has only single phase while heterogeneous mixture has two or more phases.
- Homogenous mixture can not be separated by physical methods while heterogeneous mixture can be separated out physically.
- Example of homogenous mixture is Water and sugar and heterogeneous mixture is oil and water.
Answer:
The number of oxygen in 7.9 × 10⁻¹ moles of CO₂ is 9.5116 × 10²³ atoms of oxygen
Explanation:
The given parameters are;
The number of moles of CO₂ = 7.9 × 10⁻¹ moles
The number of molecules of CO₂ in one mole of CO₂ = 6.02 × 10²³
The number of molecules, , of CO₂ in 7.9 × 10⁻¹ moles is given as follows;
= 7.9 × 10⁻¹ × 6.02 × 10²³ ≈ 4.76 × 10²³ molecules
The number of atoms of oxygen in one molecule of CO₂ = 2 oxygen atoms
Therefore;
The number of oxygen in 7.9 × 10⁻¹ moles of CO₂ = 2 × 4.76 × 10²³ ≈ 9.5116 × 10²³
The number of oxygen in 7.9 × 10⁻¹ moles of CO₂ ≈ 9.5116 × 10²³ atoms of oxygen.
