I think its the first one
Explanation:
Answer:
D. ionic sodium phosphate (Na3PO4)
Explanation:
Molecule for molecule, the solute that raises the boiling point of water the most is the one that makes the most particles in the solution. Lithium chloride breaks up into two ions (Li+ and Cl-). So does sodium chloride (Na+ and Cl-). Molecular molecules don't break up at all, so sucrose has only 1 particle per molecule. Sodium phosphate makes 4 total particles (3 Na+ ions and 1 PO4^3-). And magnesium bromide would make 3 particles (1 Mg2+ and 2 Br-). So the most is 4.

Answer:
C2H6 + 2 Cl2 = C2H4Cl2 + 2 HCl
Explanation:
Stock bottle weight to weight percentage is 37 %. This means that 1000 g of solution would contain 370 g of HCl.
therefore number of moles of HCl in 1000g - 370 g / 36.5 g/mol = 10.1 mol
the density of solution is 1.19 g/ml
volume of 1 mL weighs - 1.19 g
then 10 mL would weigh - 11.9 g
so if 1000 g contains - 10.1 mol
then 11.9 g contains - 10.1 mol / 1000 g x 11.9 g = 0.120 mol
therefore number of HCl moles in 10 mL is 0.120 mol
