AIEEE 2005 Chemistry Question Paper Mock Test

Two solutions of a substance (non-electrolyte) are mixed in the following manner: $480\text{mL}$ of $1.5\text{M}$ first solution $+520\text{mL}$ of $1.2\text{M}$ second solution. What is the molarity of the final mixture?

For the reaction: $2{\text{NO}}_2(g)\rightleftharpoons 2\text{NO}(g)+{\text{O}}_2(g)$, it is found that at $184^{\circ }\text{C}$, $K_c=1.8\times 10^{-6}$. When $K_p$ and $K_c$ are compared at this temperature, it is found that:

Hydrogen ion concentration in $\text{mol/L}$ in a solution of $\text{pH}=5.4$ will be:

A reaction involving two different reactants can never be:

If we consider that $1/6$ in place of $1/12$ mass of carbon atom is taken to be the relative atomic mass unit, the mass of one mole of a substance will:
