The 17-letter word for an instrument used to find mass is "microbalance." A microbalance is a highly sensitive device used to measure the mass of very small objects with high precision. It is commonly used in scientific research and analytical chemistry for accurate weight measurements.
The mass of an atom is obtained dividing the atomic weight of an isotope by the Avogadro number.
Atomic mass of an element is calculated based on the mass of it's protons and neutrons. This is why we get isotopes. But I think you are talking about Carbon; the periodic table is based on 12.
Hyphen Notation is the name of the element, then hyphen, then the mass number written after the element. For example, Chlorine-35.
To find the number of neutrons in an atom, subtract the atomic number (number of protons) from the atomic mass number. Neutrons are uncharged particles found in the nucleus of an atom and their number can vary for a given element based on isotopes.
Mass is measured using different types of balances.
A Triple Beam Balance is used to find the mass of an object.
periscope.
The instrument used to measure a angle is called a protractor!
A sundial
if you know the specific gravity and the volume of the substance you can find the mass.
newtons
A balance or scale is typically used to find the mass of a solid. The solid is placed on the balance, and its mass is measured in units such as grams or kilograms.
Find the mass of a known volume of the liquid and use the formula mass/volume to find the density.
Ex.: ruler, caliper, micrometer, special microscope, graduated tape, etc.
The function of a triple beam balance is to find the mass and weight of an object
A number of different instruments have been invented to do the job. They include: -- the ruler -- the yard stick -- the meter stick -- the tape measure -- the odometer -- the split-lens rangefinder -- the laser rangefinder
