How many moles are in 299000000000000000000000 molecules of Chlorine?
The given number is 299 x1021=2.99 x 1023 one mole has 6.022 x 1023 molecules. Therefore, no. of moles= 2.99 x 1023/6.022 x 1023 = .496 moles
What is the molar mass of a substance that is 23.4 percent N by mass and one molecule contains 5 nitrogen atoms?
The gram atom mass of 5 nitrogen atoms is 5 times the gram atom mass for a single nitrogen atoms, which can be found, in a periodic table or other reference, to be 14.007. Therefore the gram atom mass of 5 N atoms is 5 X 14.007 = 70.035. 23.4 % = 0.234. From the problem statement, the unknown molar mass M of the substance obeys the relationship 0.234 M = 70.035, or M = 299, to the justified number of significant digits.
What is the root mean square speed of H2S at 26 degrees Celsius meters per second?
The root mean square speed of a gas is given by the equation urms = √(3kT / m), where k is the Boltzmann constant, T is the temperature in Kelvin, and m is the molar mass of the gas. For H2S (molar mass = 34.08 g/mol), at 26 degrees Celsius (299 K), the urms would be calculated as √((3 * 1.38 x 10^-23 J/K * 299 K) / (34.08 g/mol * 0.001 kg/g)), which equals approximately 436 m/s.
What is the half life of polonium-212?
The half-life of polonium-212 is approximately 299 microseconds. This means that it takes this amount of time for half of a sample of polonium-212 to decay into a more stable element. Due to its short half-life, polonium-212 is highly radioactive and poses significant health risks.
What channel is H20 on dish network?
H2O is not a specific channel on Dish Network. However, you may be referring to the channel History 2, which is commonly known as "H2." History 2 is typically found in the 120-299 range of channels on Dish Network.
