A 9.168 M aqueous solution of H2SO4 has a density of 1.4987 g/mL at 20°C.
a. How many grams of H2SO, are in 50.0 g of this solution?
b. What is the percent by mass of this solution?
c. From the answer to (b) we see that H2SO4 is the solvent
and H2O is the solute. What is the molarity of water in
this solution?
d. What is the molality of this solution?
e. What is the osmotic pressure of this solution?

Benzonitrile (c6h5cn) is reduced to two different products depending on the reducing agent used. treatment with lithium aluminum hydride followed by water forms k, which has a molecular ion in its mass spectrum at 107 and the following ir absorptions: 3373, 3290, 3062, 2920, and 1600 cm-1. treatment with a milder reducing agent forms l, which has a molecular ion in its mass spectrum at 106 and the following ir absorptions: 3086, 2850, 2820, 2736, 1703, and 1600 cm-1. l shows fragments in its mass spectrum at m/z = 105 and 77. propose structures for k and l and choose an explanation for how this could be concluded.
