Atomic mass
The atomic mass (or weight) of silver is 107.8682 amu (atomic mass units)
The atomic mass number of aluminum is 27. The atomic mass of aluminum is 26.98115386
Cobalt has an atomic mass of 58.933195(5) while nickel has an atomic mass of 58.6934(4). Nickel has the lower atomic mass.
The atomic mass of arsenic is approximately 74.92 atomic mass units.
mesured mass-mass by subtraction/mass by subtraction * 100%
The mass of the solution is given by the volume multiplied by the density: 575 ml * 1.05 g/ml = 603.75 g. Since the solution is 18% NH4Cl, the mass of NH4Cl in the solution is 0.18 * 603.75 g = 108.675 g. Therefore, 575 ml of the solution contains 108.675 g of NH4Cl.
You can find the molar mass and then divide it from the given number for the answer. The molar mass of NH4Cl= 53.492. 66.60 g/53.492 g=1.25 mol. This means that 1.25 mol of NH4CI are in 66.60g of the substance.
The molar mass of ammonium chloride is 53.5 g/mol.
Atomic no.=no. of protons Atomic mass=no. of protons+no. of neutrons Hence, atomic mass is greater
The atomic mass is the mass of a molecule, atomic particle or sub-atomic particle.
