A 500 ml aqueous solution of na3po4 was prepared using 82g of the solute. what is the molarity​

Chemistry

Answer:

1 M

Explanation:

The molarity of a solution, M, is a measure of the concentration of that solution and it refers to the number of moles of solute (mol) per liter (L) of solution. The molarity (M) can be calculated using the formula:

M = number of moles (n) /volume (V)

In this question, a 500 ml aqueous solution of Na3PO4 was prepared using 82g of the solute.

Molar mass of Na3PO4 = 23(3) + 15 + 16(4)

= 69 + 31 + 64

= 164g/mol

Mole = mass/molar mass

mole = 82/164

mole = 0.5 mol

Volume in Litres (L) = 500 ml ÷ 1000 = 0.500L

Therefore, Molarity (M) = 0.5/0.500

Molarity = 1 M or 1 mol/L

Q26.<br>When added to 20 cm of 0.5 M sulphuric acid, which substance would give a neutral solution?​
wariber [46]

Answer:

Adding sodium or potassium hydroxide in amounts sufficient to convert all the H2SO4 into Na2SO4 would approximately neutralize the solution. The error would be the result of the imbalance between the basicity of the hydroxide and the acidity of the bisulfate (HSO4) anion. An adjustment in concentration would have to be made to achieve an accurate approximate pH of 7. But then you didn’t ask how much we would need to add.

Explanation:

<em><u>please</u></em><em><u> </u></em><em><u>mark</u></em><em><u> </u></em><em><u>as</u></em><em><u> </u></em><em><u>brainliest</u></em><em><u> </u></em>

What are the reactants and products in a chemical reaction?
Dmitrij [34]
The reactant is the chemical reaction of 2 or more different elements. 
The product is what is formed in a chemical reaction. 

Example: H + O ---->  H2O 
H + O is the reactants, and H2O is the products.

What is the relationship between nucleic acids and nucleotides?
maw [93]

The nucleotides are monomers of nucleic acid.

The nucleic acids are the macro molecules. They are two types- DNA and RNA. The nucleic acid, DNA consists of nucleotide which are monomers of the DNA. The nucleotides have three components such as pentose sugar, nitrogen bases, and phosphate.

They are the backbone of DNA. DNA is the polymer of nucleotide, and this DNA is coming under nucleic acids. The nucleotides form DNA, and DNA forms the nucleic acid. They are interlinked with each other.

Nucleic acids are the center for storing all the information. The deoxyribose nucleic acid or DNA is the center for storing all the genetic information.

The genetic material is inherited from the parents to the children. The characters are transferred from one generation to another.

The characters such as hair color, hair type, eye color are some of the genetic information that is carried from one generation to another via nucleic acids.

Nucleotide is the basic unit of nucleic acid (DNA and RNA) which store the genetic code of the cell.

It consists of sugar base (ribose or deoxyribose), nitrogenous base (A, T, G, C and U), and phosphate group.

Nucleotides (specially ATP) provides the energy for most of the cellular processes.

Therefore, with the above statements we got to know that both nucleic acid and nucleotides are genetically modified.
