The number of molecules of $CO_2$ liberated by the complete combustion of $0.1 \ mol$ of graphite in air is

While combusting in air, $4 \ g$ of $H_2$ gas was completely converted into water. If $36 \ \mu mole$ of $CO_2$ from air is dissolved into that water, what is the concentration of $CO_2$?

At constant temperature and pressure,the change in volume when $80\%\, 100\, mL$ of phosgene $(COCl_2)$ decomposes into $CO$ and $Cl_2$ is an increase of ............... $mL$.

The reaction of $1 \ mol$ of magnesium nitride with excess water gives:

What is the value of $w$ (mass of solute in grams) required to prepare a definite volume of a standard solution of known normality $(N)$?
[$N = \text{normality}$,$E = \text{equivalent weight}$,$V = \text{volume of solution in } mL$]

How many grams of $HCl$ will be present in $150 \ mL$ of its $0.52 \ M$ solution?
