Calculate the mass of $\mathrm{AgCl}$ precipitated, when $25\mathrm{ml}$ of $35\%$ solution of ${\mathrm{AgNO}}_3$ and $25\mathrm{ml}$ of $11.6\%$ solution of $\mathrm{NaCl}$ are mixed is

An alloy of metals X and Y weighs $12g\&$ contains atoms X and $Y$ in the ratio of $2: 5$. The percentage of Metal X in the alloy is $20$ by mass. If the atomic mass of X is $40$ , what is the atomic mass of metal Y.

When $20 \mathrm{g}$ of ${\mathrm{CaCO}}_3$  is treated with $20 \mathrm{g}$ $\mathrm{HCl}$, the mass of ${\mathrm{CO}}_2$ formed would be

$7.8 \mathrm{g}$ of a compound having molecular formula ${\mathrm{C}}_6{\mathrm{H}}_6$, on reacting with ${\mathrm{CH}}_3\mathrm{COCl}/{\mathrm{AlCl}}_3$ gives $8.4 \mathrm{g}$ of a product which has molecular formula ${\mathrm{C}}_8{\mathrm{H}}_8\mathrm{O}$. Calculate the percentage yield of the product ${\mathrm{C}}_8{\mathrm{H}}_8\mathrm{O}$. (Given atomic weights of $\mathrm{H}, \mathrm{C}$ and $\mathrm{O}$ respectively are $1,12$ and $16$)

The complete combustion of one mole of benzene produces grams of carbon dioxide.

If $0.2$ moles of sulphuric acid is poured in to $250\mathrm{ml}$ of water, calculate the concentration of the solution?

If the volume of $15.9 \mathrm{g}$ of carbon tetrachloride is $10\mathrm{ml}$, calculate its density.
