Why is the atomic mass scale also called the relative atomic mass scale?
All atomic masses are determined by comparing them to the mass of an atom of carbon12. One atomic mass unit equals one twelfth the mass of an atom of carbon12. That's why its called relativeatomic mass.
Is atomic masses measured in amus?
Yes, atomic masses are typically measured in atomic mass units (amu), which are defined as one twelfth of the mass of an atom of carbon-12. This unit is convenient for expressing the masses of atoms because it allows for a more manageable scale of values compared to using the actual mass in kilograms or grams.
Is this statement true or false The isotope hydrogen-1 is the standard used for the relative scale of atomic masses?
True. Hydrogen-1, also known as protium, is the standard used for the relative scale of atomic masses. Its mass is defined as exactly 1 atomic mass unit (amu) on the atomic mass scale.
What nuclide is used as the standard in the relative scale for atomic masses and What is it's assigned atomic mass?
Carbon-12 (12C) is used as the standard in the relative scale for atomic masses, and its assigned atomic mass is 12 atomic mass units.
What nuclide is used as standard relative scale for atomic masses?
Carbon-12 is used as the standard relative scale for atomic masses. This is defined as having a mass of exactly 12 atomic mass units (u). Other elements are compared to this standard to determine their atomic masses.

A device that works by comparing the mass of an object known a mass called a?
The device you are referring to is likely a balance scale. The balance scale measures the mass of an object by comparing it to a known mass placed on the other side of the scale. When the two masses are equal, the balance scale is level, indicating that the masses are the same.
What instrument can be used to compare the masses of two objects?
A balance or a scale can be used to compare the masses of two objects. By placing the objects on either side of the balance or scale, you can visually determine which object has a greater or lesser mass.
What temperature scale is not really used in science?
Science does not use the Fahrenheit scale, it uses the Celsius scale or the Kelvin scale instead.

True. Hydrogen-1, also known as protium, is the standard used for the relative scale of atomic masses. Its mass is defined as exactly 1 atomic mass unit (amu) on the atomic mass scale.

A chemical change is any change that?
In a macrscopic scale: alters colour, scent, texture.In a microscopic scale: Break bonds between atoms in a molecule and/or forms new bonds between atoms.
If you are using a balance scale than you are measuring mass in what?
You are measuring mass in any system for which you have standard masses.
Why is not a reason why the mass of an atom is expressed in atomic mass units rather than in grams?
Atoms are very tiny. Expressing their masses in grams would require unusual prefixes like "-yocto" or cumbersome scientific notation. One AMU is equal to 1.66*10-24g. It's easier to compare the masses of atoms by using a special unit.
How can you find out weight of an unknown object by using standard masses by scale or by ruler?
To find the weight of an unknown object using standard masses and a scale, you can use a balance scale. Place the unknown object on one side and add standard masses to the other side until the balance is achieved. The sum of the standard masses used will be equal to the weight of the unknown object. To find the weight of an unknown object using a ruler, you can use the concept of density. Measure the dimensions of the object to calculate its volume, then weigh the object to find its mass. Using the formula density = mass/volume, you can determine the weight of the object by multiplying its volume by the density of the material it's made of.
