Atomic mass Calcium = 40.078 a.m.u
40.078 g ---------------- 6.02x10²³ atoms
165 g -------------------- ??
165 x ( 6.02x10²³) / 40.078 => 2.47x10²⁴ atoms
hope this helps!
<span>One atom of silicon can properly be combined in a compound with two atoms of oxygen.</span>
Proton: positive- mass equal to neutron
Electron: negative- mass 1/1840 mass of proton
Neutron: no charge- same mass as proton
The answer is True because they are formed of deposition.
Where is the model? I do know salt water is a mixture though
