v. dexamethasone in the German National Formulary [2] are inconsistent and can lead to differences of about 25% in calculating the dosage on a molar basis. The authors recommend a standardization of declarations of the contents of i. v. glucocorticoids....
To find the number of moles of helium gas needed to achieve an internal energy of 100 Joules at a temperature of 300 K and a pressure of 1.00 atm, we can use the formula for the internal energy of a monatomic ideal gas. 1. Identify the
moles of water in one drop = 0.002775 moles Using Avogrado's Number Finally, useAvogadro's numberto determine the number of molecules in a drop of water. Avogadro's number tells us there are 6.022 x 1023molecules of water per mole of water. So, next we calculate how many molecules there...
