An aqueous solution contains 25.0g of glucose, C6H12O6, in 300.0 mL solution. The density of this solution is 1.08 g/mL. Calculate the molarity, molality, weight percent, and mile fraction of the glucose solution.
An automobile has a wavelength that is not measurable by human standards. If the car has a mass of 4000 lbs (1.81 x 103 kg) and travels at 60 miles/hr (26.8 m/s), calculate the wavelength of the car.
The mass spectrum of a compound that contains two bromine atoms gives isotope peaks with relative intensities of 1:2:1 for the M, M+2 and M+4 peaks, respectively. Explain why.
