Suppose 1.94g of sodium bromide is dissolved in 200.mL of a 57.0mM aqueous solution of silver nitrate. Calculate the final molarity of bromide anion in the solution. You can assume the volume of the solution doesn't change when the sodium bromide is dissolved in it.Round your answer to 2 significant digits.

Compound a C9H12, undergoes nitration to give three products. The 1H NMR spectrum of A shows a complex three-proton multiplet at 6.92-6.99? And a nine-proton singlet at 2.34. Explain what is the structure of A
A large gas flask is found to weigh 143.567 g. it is then filled with gas to a pressure of 735 torr at 31 C and found to weigh 1067.9 g (the density of water is 31 C is 0.997 g/mL). Assuming that the ideal gas equation applies, calculate the molar..
