Calculating Atomic Mass and Moles for Magnesium, Potassium, Carbon, Phosphorus, and Sodium

This guide provides step-by-step solutions for calculating atomic mass and converting between grams and moles for various elements. We determine the atomic mass of magnesium by combining the contributions from isotopes and discuss significant figures in measurements. The guide also includes examples of converting grams of potassium to moles, moles of carbon to grams, identifying the number of phosphorus atoms in a given mass, and calculating grams of sodium based on the number of atoms. Perfect for chemistry students!

  1. Problems

  2. Calculate the atomic mass of magnesium based on the following information:

  3. .7870 x 23.985 = 18.876195 • .1013 x 24.986 = 2.5310818 • .1117 x 25.983 = 2.9023011 • Add them together: • 18.876195 + 2.5310818 + 2.9023011 = 24.309578 • How many significant figures should the answer have?

  4. Try again with Uranium

  5. You should have gotten an answer of 238.029 amu • Convert 23.97 grams of potassium to moles.

  6. Convert 4.29 moles of carbon to grams.

  7. How many atoms of phosphorous are in a 2.76 gram sample?

  8. How many grams of sodium are there if you have 4.76 x 1023 atoms of sodium?
