The number of atoms in 0.1 mole of a triatomic gas is:

Suppose the elements X and Y combine to form two compounds $X{Y_2}$ and ${X_3}{Y_2}$. When 0.1 mole of $X{Y_2}$ weights 10 g and 0.05 mole of ${X_3}{Y_2}$ weights 9 g, the atomic weights of X and Y are

If $4.6$ g of formic acid and $9.0$ g of oxalic acid react with concentrated $H_2SO_4$, and the resulting gaseous mixture is passed through $KOH$ pellets, what mass of gas (in grams) will remain at STP?

One mole of $\;{\rm{C}}{{\rm{O}}_2}$ contains:

The production of 10 moles of ammonia by the Haber process requires how many moles of hydrogen gas, assuming complete reaction?

The mass of 2.5 g.atom of oxygen is

What is the mass of one mole of carbon dioxide (CO2)?

A gaseous mixture contains oxygen and nitrogen in the ratio of $1:4$ by weight. Therefore, the ratio of their number of molecules is:

In the Haber process, if 40 moles of ammonia are formed, the number of moles of hydrogen consumed is?

A mixture of $2.3$ g formic acid and $4.5$ g oxalic acid is treated with conc. $H_2SO_4$. The evolved gaseous mixture is passed through $KOH$ pellets. The weight (in g) of the remaining product at STP will be

Calculate the mass (in g) of the gaseous product remaining at STP when a mixture of $9.2$ g formic acid and $18$ g oxalic acid is treated with conc. $H_2SO_4$ and then passed through $KOH$ pellets.
