Grade 12Physical Chemistry
Sodium metal was contaminated with sodium oxide and sodium chloride . A sample of this metal 1.00g was dissolved in water producing 4.95×0^-4 m 3 of h2 gas at 298 K and 980000Pa . The resulting solution was made to a volume 250cm3 with water & 25cm3 of this is neutralized by 37.3cm3 of 0.112M HCl calculate the mass percentage of na2O in sample
