What scientific instrument was used to discover that not all atoms of neon have the same mass?
The mass spectrometer was used to discover that not all atoms of neon have the same mass. This instrument separates and measures atoms based on their mass-to-charge ratio, allowing scientists to identify isotopes of elements like neon that have different masses.
Why do we use the mole as a unit of measurement for counting atoms?
The mole is used as a unit of measurement for counting atoms because it allows us to work with a convenient and consistent quantity of atoms. One mole of any substance contains the same number of atoms, which is approximately 6.022 x 1023. This large number makes it easier to work with extremely small particles like atoms and molecules in chemical reactions and calculations.
According to the law of conservation of mass if two atoms of hydrogen are used as a reactant how many atoms of hydrogen must be part of the product?
If two atoms of hydrogen are used as a reactant, the law of conservation of mass dictates that the total number of hydrogen atoms in the products must also be two. This means that the number of hydrogen atoms remains the same before and after the reaction, so two atoms of hydrogen must be part of the product.
What is the mass of 1 mole of carbon atom?
We use the equation: Mass = Number of moles * Molecular or atomic mass Since the number of moles is 1 ("one mole of carbon-12 atoms") and the atomic mass of carbon-12 atoms is 12, hence the mass would be 12 grams. Note that the unit grams (g) is used here, as it is the SI unit for mass measurement. I hope this is useful! :)
How many atoms are in 1 amu and 1 g of hydrogen?
There is 1 atom in 1 atomic mass unit (amu) of hydrogen, as amu is a unit used to express the mass of individual atoms. In 1 gram of hydrogen, there are approximately 6.022 x 10^23 atoms, which is equivalent to Avogadro's number and is known as a mole of atoms.
What units are used to measure the mass of atoms?
AMU=Atomic Mass Unit

Which subatomic particle has such a small mass that is not used to calculate the atoms atomic mass?
electron
What method of measuring mass is easier and more widely used than the inertial method?
The gravitational method of measuring mass, using a balance or scale, is typically easier and more widely used than the inertial method. This method compares the force of gravity acting on an object to a known standard mass, making it a practical and common way to determine mass in various settings.
The unit used for counting umbers of atoms ions or molcules is the?
You generally count them in moles, which is actually a number: 6.02X1023.
Can Atomic mass be used to determine molecular mass?
Yes, the accumulation of atomic masses of the atoms within a molecule is the molecule's molecular mass.
What is the method used to determine the measured mass of an object accurately?
The method used to determine the measured mass of an object accurately is by using a calibrated scale or balance. The object is placed on the scale, and the reading displayed on the scale is the measured mass of the object.
What is the small unit of mass used to label the weight of atoms?
The unified atomic mass unit (symbol: u) or dalton (symbol: Da)

What do Elements Atoms Molecules and Mass have in common?
For atoms, after IUPAC rule, the term used is atomic weight. The unit is "unified atomic mass unit", not included in SI.For molecules the term is molecular (molar) mass. The unit is kg/mol.
How do you determine the mass of an irregular shaped object using displacement method?
The displacement method is used to determine volume. However, if you know the density, the displacement test can give volume, which is used to work out mass by the formula m = dV
What would you expect the average mass of a penny to be the same whether it is calculated by method 1 or method 2?
The average mass of a penny should be the same regardless of the method used if both methods are accurate and precise. The mass of the penny is an intrinsic property that should not change based on how it is calculated.
