How does Avogadro's number relate to the atomic mass and moles of an element? Avogadro's number can be used to convert the atomic mass of an element to the mass of one mole of that element The mass of one mole of an element can be used to convert the atomic mass of that element to Avogadro's number. Avogadro's number is not related to the atomic mass of an element or the mass of a mole of that element. The...

Esay recorded the following data for Avogadro's number experiment. He concluded that the average calibration number of drops from dropper per mL is seventy-seven. Next, Esay determined it took twelve drops of stearic acid solution to form the monolayer. Density of stearic acid = 0, 85 g/mL Concentration of stearic acid solution= 1.42 times 10^-4 g/mL Diameter of the vessel 14.5 cm Molar mass of stearic acid = 284 g.mol a. Calculate the volume of stearic acid needed to form...

For the gas constant, use R = 8.314 J/mol-K For Avogadro's number, use N_0 = 6.022 times 10^23 molecules. Be careful of units! All the conversions you need are in the information section of the lab. Suppose the volume of the syringe is 47.5 cc. You measure the pressure as 1.58 atm, and the temperature as 19.8 degree C. Assume: the diameter of the plunger on the syringe is 1.44 cm. Find the number of moles of gas in the...

1. Avogadro's number Na is defined as the number of particles (e.g. 1 mole) such that the mass of a mole of particles with mass equal to 1 atomic mass unit u is exactly equal to 1 gram. (Note that the atomic mass unit u is defined as 1/12 of the mass of an atom of carbon 12 (2C) and is approximately equal to the mass of a proton.) Using the following values, which are given to 5 significant figures,...
