what is the diff between atoms and molecule?

50 names of compounds and their chemical formula

Define mole concept?

what are the limitations of dalton's atomic theory?

gve list of monovalent cations/anions

diavalent cations /anions

trivalent cations/anions.

calculate the mass of 1 molecule of of oxygen gas : given [at mass of o = 16u,N_{A} =6.022 * 10^{23 }mol^{ -1]}

Calculate the number of molecules of sulphur (S_{8}) present in 16 g of solid sulphur.

In this question why do we multiply the avagadro number? We are to find number of molecules, so why we take out moles?????????????? plzzzzzz reply

how can we find the valency of polyatomic ions like SO4, SO3, CO3,PO4 etc.?

how to calculate the valency of any compound?

calculate the molar mass of nitric acid HNO3 (H=1,N=14,O=16)

Calculate the mass of 1 atom of silver and 1 molecule of carbon dioxide.

valency table

calculate the no. of aluminium ions present in 0.051g of aluminium oxide

give me a list of atomicity of all elements

prove the formula K.E.=1/2mv^{2}
