Calculate the total mass of the protons and electrons in 19/9F. Use 1.007825 amu as the mass of 1/1H(mass of a proton and an electron). Express your answer in atomic mass units to 6 significant figures. Calculate the total mass of the neutrons in 19/9F. Use 1.008665 amu as the mass of 1/0N(mass of a neutron). Express your answer in atomic mass units to 7 significant figures. Calculate the mass defect of 19/9F. Use 18.9984 amu as the actual mass of 19/9F. Express your answer in atomic mass units to the fourth decimal place.
What is the total number of moles of Ca needed to react completely with 4.0 moles of H2O?
An impure sample of potassium hydrogen phthalate, KHP, having a mass of 111.07 g was dissolved in water. This acid sample was neutralized by the addition of 310.0 mL of 0.250 M NaOH
Question1 : If a sample of water from a pond is to be analyzed for whatever chemicals it may contain (including organic compounds and metal containing species), give a very brief, but specific description of the protocol that would be best used, i..
The probability of filling a 3p orbital relative to the 3s orbital is 3/1. Assuming that the total Mg+ population in a given atomization source is 3.5 x 10^18 ions at any given time, what would be the number of ions that are in the excited 3p stat..
