Briefly explain formality in solution.

Zielflug [23.3K]

Answer:

Both molarity and formality express concentration as moles of solute per liter of solution. Formality is a substance's total concentration in solution without regard to its specific chemical form. ... The formality of a solution is defined as the number of formula mass of any solute dissolved in 1 litre of solution.

Show, in a step by step fashion, your calculations to determine the percent

marusya05 [52]

The percent by volume of a solution : 19.23%

<h3>Further explanation</h3>

Given

50 ml of ethanol

210 ml of water

Required

The percent by volume of a solution

Solution

Percent Volume (% v/v) : volume (ml) of solute/100 ml of solution ⇒ ratio of the volume of the solute to total volume of the solution

$\tt \%solute(v/v)=\dfrac{solute~volume}{solution~volume}\times 100\%$

solute= Ethanol

solvent=water

Solution = solute+solvent

Total volume of the solution :

$\tt =volume~of~Ethanol+solume~of~water\\\\=50~ml+210~ml\\\\=260~ml$

Percent by volume :

$\tt \%volume=\dfrac{50}{260}\times 100\%\\\\\%volume=19.23\%$

A compound has a molar mass of 100 g/mol and the percent composition (by mass) of 65.45% C, 5.45% H, and 29.09% 0. Determine the

coldgirl [10]

Answer:

B) C3H3O and C6H6O2

Explanation:

Given data:

Molar mass of compound = 100 g/mol

Percentage of hydrogen = 5.45%

Percentage of carbon = 65.45%

Percentage of oxygen = 29.09%

Empirical formula = ?

Molecular formula = ?

Solution:

Number of gram atoms of H = 5.45 / 1.01 = 5.4

Number of gram atoms of O = 29.09/ 16 = 1.8

Number of gram atoms of C = 65.45 / 12 = 5.5

Atomic ratio:

C : H : O

5.5/1.8 : 5.4/1.8 : 1.8/1.8

3 : 3 : 1

C : H : O = 3 : 3 : 1

Empirical formula is C₃H₃O.

Molecular formula:

Molecular formula = n (empirical formula)

n = molar mass of compound / empirical formula mass

Empirical formula mass = 12×3 + 1.01 ×3 + 16×1 = 55.03

n = 100 / 5503

n = 2

Molecular formula = n (empirical formula)

Molecular formula = 2 (C₃H₃O)

Molecular formula = C₆H₆O₂

What is the percentage of water in the following compound? answer using one decimal place. sodium carbonate decahydrate, na2co3

ehidna [41]

The percentage by mass of water in Na2CO3.10H2O from the calculation is 62.9%

<h3>What is percentage by mass?</h3>

The term percentage by mass refers to the amount of a particular moiety by mass in a molecule.

In this case, we know that the molar mass of Na2CO3.10H2O is 286 g/mol the molar mass of the 10 moles of water is 180 g/mol hence the percentage by mass of water in the compound is; 180 g/mol /286 g/mol * 100/1 = 62.9%
