There are approximately 1,200 beads in a mass.
a mass is 1200 pieces.
Grams are a measure of mass.
Atomic Mass: 74.9216 amu
The sun is about 19,000 times the mass of Neptune.
The mass of a die depends on what it is made of and how big it is. The mass of dice also depends on how many there are.
This question is a little ambiguous. If you mean 'how many elements have mass,' the answer is 'all elements have mass.' There are 117 known elements, and scientists theorize that there may be as many as 130 or more.
Yoy need to know the molar mass of this solute and the mass of the solute:moles = total mass/molar mass
It tells you the mass of how many protons and how many neutrons plus the tiny mass of the electrons. The electrons are about .0016 amu so they still have mass
From many years this affirmation is not considered valid.

Not many things have no mass however Photons (Light Particles) have no mass and therefore they travel at the speed of light.
The molar mass of a compound is typically a multiple of its empirical formula mass, depending on the molecular formula. To determine how many times heavier the molar mass is than the empirical formula mass, you can divide the molar mass by the empirical formula mass. This ratio will yield a whole number that represents how many times the empirical formula fits into the molecular formula. For example, if the molar mass is 60 g/mol and the empirical formula mass is 15 g/mol, then the molar mass is 4 times heavier than the empirical formula mass.
