I got one wrong but not sure which one is wrong

12. A 5.000 gram sample of Na2CO3 X H₂O was heated to a constant weight of 1.853 grams. Na2CO3 = 106 g/mole & H₂O = 18.0 g/mole a] Determine the percentage of water in the sample. [1] Na Co alu 0.1029 b] Determine the value of "X" in the formula: Na2CO3 X H₂O. 5.000g Naz Naz CO₂ Naz [2]

This is all I can figure out please help

part B please!!

Going to need help on 1., 2., 3. and 4.

What is the melting point of the substance modeled by this heating curve? F 150 135 120 D E 105 90 75 C 60 45 30A 15 Heat (kJ) Created by E. Lee for Virtual Virginia (2021) Temp. (°C) B

Constants Periodic Table A sample of a liquid substance called jojane- named after the narcissitic scientist Dr. Joey Negdirf who discovered the substance- was brought back to Earth following a five year mission exploring the Andromeda galaxy. In their lab on earth, Dr. Negdirf's team conducted a number of experiments to determine the physical properties of the substance. Part A Using the Dumas method to determine the molar mass of a volatile liquid, a sample of jojane was vaporized in a 2.000 L vessel and heated to 401.6 K at 1.150 bar. The mass of the vapour in the vessel was 5.106 g. Determine the the molar mass of the compound. 60.10 g mol-1 O 88.14 g mol-1 O 72.09 g mol-1 O 74.12 g mol-1
