The relation between molecular (formula) mass and molar mass Page 4 4 • To obtain one mole of copper atoms (6.02 x 1023 atoms), weigh out 63.55 g copper. The molar mass (M) of a substance is the mass of one mole of entities (atoms, molecules, or formula units) of the substance.

Answer:
C
Explanation:
cold thinks sink and are more dense, warm things rise and are less dense
if my answer helps please mark as brainliest.
Well I'm not sure about the first one, however the 2nd one is false, an atom can still react with other atoms if it has a neutral charge. and the third one is false, because only the electrons on the furthest out ring can react with other atoms, these electrons are called valence electrons, and the ones on more inside rings are full so they cannot be bonded with other atoms
Answer:
0.00714 g
Explanation:
We know that the volume of one mole of a substance is 22400 cm^3
Thus;
1 mole of sulphur occupies 22400 cm^3
x moles of sulphur occupies 5.0 cm3
x = 5.0 cm3 * 1 mole/22400 cm^3
x = 2.23 * 10^-4 moles
Molar mass of sulphur = 32 g/mol
Mass of sulphur = 2.23 * 10^-4 moles * 32 g/mol
Mass of sulphur = 0.00714 g
