Answer:
164 g
Explanation:
Asnwer : Empirical formula of a compound is :
Given information : C = 64.3 % , H = 7.2 % , O = 28.5 %
Step 1 : Convert the given percentage (%) to grams.
Explanation : Let the total mass of the compound be 100 grams.
Mass of C = 64.3 g
Mass of H = 7.2 g
Mass of O = 28.5 g
Step 2 : Convert the grams of each compound to moles.
Molar mass of C = 12.0g/mol
Molar mass of H = 1.0 g/mol
Molar mass of O = 16.0g/mol
Moles of C = 5.36 mol
Moles of H = 7.2 mol
Moles of O = 1.78 mol
Step 3 : Find the mole ratio of C , H and O
Mole ratio is calculated by dividing the mole values by the smallest value.
Mole of C = 5.36 mol , Mole of H = 7.2 mol , Mol of O = 1.78 mol
Out of the three mole values , mole value of O that is 1.78 mol is less , so we divide all the mole values by 1.78 mol.
C : H : O = 3 : 4 : 1
So empirical formula of the compound is or
Answer:
When the graduation line denotes the volume contained in the calibrated vessel, the ware is marked “TC”. When the graduation line indicates the volume delivered from the vessel, the ware is marked “TD”.
As the temperature of a liquid or stable will increase its vapor strain additionally will increase. Conversely, vapor strain decreases because the temperature decreases.
The better the vapor strain of a substance, the extra the awareness of the compound withinside the gaseous section and the extra the quantity of vaporization
. Liquids range substantially of their vapor pressures. substance with a excessive vapor strain at everyday temperatures is regularly called volatile. The strain exhibited through vapor gift above a liquid floor is referred to as vapor strain. As the temperature of a liquid will increase, the kinetic strength of its molecules additionally will increase.

Answer:
The ratio of solution 1 to solution 2 is 24.20 to 100.00.
Explanation:
We will mix V₁ (L) of solution 1 with V₂ (L) of solution 2 to get the final solution.
So the mole concentration in the final solution is calculated as below, note that C₁ is the concentration of solution 1, and C₂ is the concentration of solution 2
Then we can calculate for the ratio
