How many molecules are there in 6.07g of ag2co3

There are molecules in 6.07 grams of silver carbonate.

Explanation:

Moles of a compound is defined as ratio of mass of the compound to the molar mass of the compound.

1 mole corresponds to numbers of atoms or molecules or ions.

= Avogadro number = atoms, molecules/ions

Number of molecules particles in 'n' moles of compound:N

Mass of silver carbonate,m = 6.07 g

Molar mass of carbonate ,M= 276 g/mol

Moles of silver carbonate = n

Number of molecules of silver carbonate in 0.02199 moles.

There are molecules in 6.07 grams of silver carbonate.

answer: the value of enthalpy change will be -152.80 kj.

solution:

pressure = 1atm , temperature = = 298 k

given that pressure and temperature are same in both gases , the number of moles of both gases can be determined by the ideal gas equation.

according to reaction 3 moles no are reacting with 1 mol of ,then 0.49 mol of no will react with moles of ozone that is 0.16 moles of ozone. since, no is limiting reagent and is an excessive reagent.

enthalpy change for the reaction between the given volumes of the gases is :
