2.59 atoms?? Oh well.

2.59 atoms Li (1mol Li/6.022 X 10^23 )(6.941 grams Li/1mol Li ) = 2.98 X 10^-23 grams

What is the gram molecular mass of sulfur molecule?

The gram molecular mass of a sulfur molecule (S8) is 256 grams per mole. This is calculated by adding up the atomic mass of each sulfur atom in the molecule. Each sulfur atom has an atomic mass of 32 grams per mole, and there are 8 sulfur atoms in a sulfur molecule.


What is the maximum mass of S8 that can be produced by combining 75 grams of each reactant?

The molar mass of S8 is 256 g/mol. To calculate the maximum mass of S8 that can be produced, first determine the limiting reactant by converting the masses of the reactants to moles. Then, use the stoichiometry of the reaction to find the mass of S8 produced from the limiting reactant.


What is the density of a block of marble that occupies 256 cm3 and has a mass of 920 g?

The density of the marble block is given by the mass divided by the volume. In this case, the density is 920 g / 256 cm3, which equals 3.59 g/cm3.


Mendelevium -256 and mendelevium-258 what is the difference between the nuclei of these two isotopes?

The difference between mendelevium-256 and mendelevium-258 lies in their atomic mass, with mendelevium-256 having 256 nucleons (protons and neutrons) and mendelevium-258 having 258 nucleons. This means that mendelevium-258 has two more neutrons in its nucleus compared to mendelevium-256.


A metal bar has a volume of 32 cm3 The mass of the bar is 256 g What is the density of the metal?

IF I remember correctly, density is mass divided by volume. So.. D=M/V D=256/32 D=8 g/cm I think g/cm is the unit. I could be wrong.
