What is the mass of 1.0 x 1012 molecules of O2?

To calculate the mass of 1.0 x 10^12 molecules of O2, you need to first determine the molar mass of O2, which is approximately 32 g/mol. Then, divide the number of molecules by Avogadro's number to convert to moles, and finally multiply by the molar mass to find the mass. The mass of 1.0 x 10^12 molecules of O2 would be approximately 0.53 grams.


What is the mass in grams of 2x1012 atoms of potassium?

To calculate the mass of 2x10^12 atoms of potassium, you first need to find the molar mass of potassium (39.10 g/mol). Then, divide the number of atoms by Avogadro's number to get the moles of potassium. Finally, multiply the moles by the molar mass to find the mass in grams, which in this case would be 0.01566 grams.


What is the melting point of blue tourmaline?

Between 1012 and 1102 degrees Celsius. The melting point varies greatly since there are many different compositions of tourmaline.


What is the mass in grams of 1.00 X 1012 lead (Pb) atoms?

To find the mass of 1.00 x 10^12 lead atoms, you would first determine the molar mass of lead (Pb), which is 207.2 g/mol. Then, divide the total number of atoms by Avogadro's number to get the number of moles, and finally multiply by the molar mass to get the mass. So, the mass of 1.00 x 10^12 lead atoms is approximately 3.14 x 10^-9 grams.


How many gold atoms would have to be lined up to span 4.0 mm?

The radius of gold is 144 picometers, so....,144 picometers (103/1012)= 1.44 X 10 -7 mm------------------------so,4.0 mm/1.44 X 10 -7 mm= 2.8 X 107 * 2 ( because you need to double radius to get diameter end to end )= 5.6 X 107 gold atoms lined up======================
