Yes they are; they are not the constants that they were once considered to be.
Relative atomic mass, also called atomic weight, is listed on the periodic table for each element. There is no element listed on the periodic table with a relative atomic mass of 15.5.
The relative formula mass of ethanol (C2H5OH) is 46 g/mol.
The relative formula mass of a hydrogen molecule (H2) is calculated by adding the atomic masses of the two hydrogen atoms. Each hydrogen atom has an atomic mass of approximately 1, so the relative formula mass of a hydrogen molecule is 2.
The anhydrous copper sulfate (CuSO4) has a molar mass of 159,62.
Carbon is a non metal element. Atomic number of it is 12.
Mass IS relative to the speed you are going.
relative atomic mass
relative Atomic Mass
electron = relative charge = 1- relative mass = 1/1840 proton = relative charge = 1+ relative mass = 1 neutron = relative charge = 0 relative mass = 1
It is a measure which gives the relative mass of an element (or compound) - relative to 12C having a mass of 12.
the relative atomic mass for the element potassium is 39.0983
The relative atomic mass of copper is approximately 63.55. To calculate the relative formula mass of copper, you sum the atomic masses of its atoms, which in this case would just be the atomic mass of copper. Therefore, the relative formula mass of copper would be 63.55.
Approximately 4.01
The relative atomic mass of magnesium is approximately 24.305.
The relative formula mass of iodine is 253.8 g/mol.
Relative atomic mass, also called atomic weight, is listed on the periodic table for each element. There is no element listed on the periodic table with a relative atomic mass of 15.5.
The relative atomic mass of sulfur is 32.06 g/mol and the relative atomic mass of oxygen is 16.00 g/mol. Therefore, the relative molecular mass of SO2 (sulfur dioxide) is 32.06 + (16.00 x 2) = 64.06 g/mol.
