If Avogadro's number is $A_0$,the number of sulphur atoms present in $200 \, mL$ of $1 \, N \, H_2SO_4$ is

The $\Delta H^o$ of combustion of $C_4H_{10(g)}$ is $-2650 \ kJ \ mol^{-1}$. The amount of heat evolved at constant pressure that can be obtained by burning $5.8 \ kg$ of $C_4H_{10}$ is approximately:

One mole of methanol when burnt in excess of $O_2$ releases $723 \ kJ \ mol^{-1}$ of heat. If $1 \ mol$ of $O_2$ is used,what will be the amount of heat evolved in $kJ$?

The formula of a gaseous hydrocarbon which requires $6$ times of its own volume of $O_{2}$ for complete oxidation and produces $4$ times its own volume of $CO_{2}$ is $C_{x}H_{y}$. The value of $y$ is $......$ .

If one wants to make methanol out of synthesis gas,what should be the ratio of the gaseous components in the synthesis gas?

The density of $SO_2$ at $STP$ is ......... $g/L$.
