The total pressure of a mixture of non-reacting gases \( X(0.6\,\text{g}) \) and \( Y(0.45\,\text{g}) \) in a vessel is \( 740\,\text{mm of Hg} \). The partial pressure of the gas \( X \) is \( \_\_\_\_ \) \( \text{mm of Hg} \). (Nearest Integer)
(Given: molar mass \( X = 20 \) and \( Y = 45\,\text{g mol}^{-1} \))
