5.4 g of a metal (M) reacts with chlorine to form \(26.7\,\text{g}\) of metal chloride. What is the weight (in g) of M that reacts with \(48\,\text{g}\) of oxygen?

1.5 g of an organic compound was analysed by Kjeldahl's method for estimation of nitrogen. The ammonia liberated was passed into 30 mL of 1N HCl solution. The remaining HCl was further neutralised by 120 mL of N/10 NaOH solution. The percentage of nitrogen in the compound is:

0.42 g of an organic compound containing C, H and O gave on combustion 0.942 g of $CO_2$ and 0.231 g of $H_2O$. The empirical formula weight of the compound is (At.wt: $C=12$ u, $H=1$ u, $O=16$ u)

An organic compound has the empirical formula CH$_2$O. Its vapour density is 45. The molecular formula of compound is
