Question

Calculate the mass of sodium hydroxide obtained by the reaction of 2.3g sodium with excess water​

Answer 1

Answer:Ted Krapkat, 46yrs as a chemist in the cement & aluminum industries. Since chlorine is a diatomic gas (Cl), its molar mass is 2 * 35.45 = 70.90 g/mol. Molar mass of NaCl = (22.99 + 35.45) = 58.44 g/mol. The equation for the reaction tells us that, one mole of Cl will produce two moles of NaCl.
