6) A hydrate of NaCo (107 g/mol) has a mass of 6.36 g before heating. After heating, the mass of the anhydrous compound is found to be 3.22 g. Determine the formula of the hydrate? (A) Na CO,. 21:0 (B) Na,CO, 4130 (C) Na:C06H 0 (D) Na CO,. 12H2O (4) Write Tor F? [31 1. > The obscrvation of the reaction between Na:CO, and AgNO, is evolution of CO, gas 2.0 A 1.5 mL of alcohol weight 960 mg has a density equal 0.64 g/mL.. 3. The alur crystals should be washed by pure water during vacuum filtration 410 The volume of liquid should be read at the bottom of meniscus. All chemicals tased in experiments can be discarded into the sink. A simple filtration was performed to collect alum ctystals.
