How many grams of helium are in 16 moles
WebOne mole of an ideal gas occupies 22.71 L at STP. Thus, its molar volume at STP is 22.71 L. Example Problem. A 6.00 L sample at 25.0 °C and 2.00 atm contains 0.500 mol of gas. If we add 0.250 mol of gas at the same pressure and temperature, what is the final total volume of the gas? Solution. The formula for Avogadro's law is: #V_1/n_1 = V_2/n_2# WebHow many atoms are there in 5.8 mol helium? a. ... The atomic number of sulfur is 16. Compared with a mole of oxygen, ...
