FORMULA used:  

Explanation:

Given,

Mass(solute)=45 g

Volume= 250 cm³

Molar mass of Glucose (C₆H₁₂O₆)

6×12+12×1+6×16

= 180 u.

Using formula of Molarity we GET,

Answer:

Nitric acid has the chemical formula HNO 3, so the MASS number would be the sum of the atomic masses for hydrogen (1), nitrogen (14) and three lots of OXYGEN masses (3x16). So, (1+14+48) = 63.

Answer:

Interparticle force of attraction can be DEFINE as the force of attraction exerts between particles(ATOMS,molecules). ... for ex- In SOLID particles are very close so they interparticle space is very less while in gas particles are very FAR from each other so they interparticle space is large.

ANSWER:

NO2 is called double ANHYDRIDE because two acids NITROUS ACID and nitric acid are FORMED when it react with water.... Answer: NO2 is called double anhydride because two acids nitrous acid and nitric acid are formed when it react with water.

Explanation:

Mixed anhydride or double acid anhydride is the compound that reacts with water to form a mixture of two acidic anhydride. Two oxides of nitrogen are acid anhydrides; that is, they react with water to form two nitrogen-containing oxyacids.

what is your QUESTION I cannot UNDERSTAND it

ANSWER:

what do we have to TELL PLEASE ELABORATE

Answer:

This is very general question!

Explanation:

let's say,

carbon dioxide is reacted with calcium hydroxide

CO2 + Ca(OH)2 --> CACO3 + H2O

you got calcium CARBONATE and water, when you ADD Atomic mass of CaCO3 (100g/mol) and water (18g/mol) total atomic mass will be 118g/mol which is equal to atomic mass of tin!

so this question is very general, you can do with any REACTION you want to!

as PER the above Reaction, X will be Tin!

Answer:

Acid catalyzed HYDRATION of alkenes involves replacing the pi BOND on an alkene with a water molecule. This is done by adding an alcohol to the more substituted CARBON ATOM, and hydrogen to the less substituted carbon atom. This REACTION follows Markovnikov's rule and may undergo a carbocation rearrangemen.

Dobereiner's triads was first attempt to arrange elements in a periodic way by considering 3 elements in a way that, average mean Atomic MASS of first and last elements are equal to atomic mass of middle one.

where as, in NEWLANDS Octaves, he has arranged elements based on the same atomic masses but in INCREASING order, & When he placed 8th ELEMENT, it will be having similar properties of 1st element!

that's the main difference here!
