An El Paso FM radio station broadcasts classic rock at a frequency of 95.5 MHz. Find the wavelength in nm of these radio waves.
A 74.8 g sample of copper at 143.2°C is added to an insulated vessel containing 165 mL of glycerol, C3H8O3 (l) (d = 1.26 g/mL), at 24.8°C. The final temperature is 31.1°C. The specific heat of copper is 0.385 J g-1°C-1. What is the heat capacity o..
Which indicator would be the best to use when titrating ammonia with nitric acid? Kb of NH3 is 1.8 x 10-5.
Calculate the empirical formula for a chemical compound which gives the following analysis: 12.6 percent lithium, 29.2 percent sulfur, and 58.2 percent oxygen.
Calculate the mass (grams) of KHP needed to react with 40. mL of 0.10 M NaOH. B. If 0.7528 g of KHP standard were titrated with NaOH and the endpoint was reached at 36.33 mL
A vessel containing 45.0 cm3 of helium gas at 25°C and 106 kPa was inverted and placed in cold ethanol. As the gas contracted, ethanol was forced into the vessel to maintain the same pressure of helium.
Dry air (0% humidity) is approximately 78% N2, 21% O2, and 1% Ar by moles. Calculate the molar mass and density of dry air at 0 °C and 1.0 atm. Assume ideal behavior and use two significant figures in your answers.
