Carbon molar mass=12
carbon mass in the above question =6
mole=number of atoms/6.02x10²³
6/12= number of atoms/6.02x10²³
number of atoms=1/2 x6.02x10²³
number of atoms= 6.02 x10²³/2
number of atoms=3.01x10²³
2H3PO4 + 3Ca(OH)2 ➡ Ca3(PO4)2 + 6H2O.
Hence salt formed is Ca3(PO4)2.
Hope this helps, have a nice day!
Answer: 57 neutrons
Explanation: Ruthenium has an atomic number of 44, meaning it has 44 electrons, 44 protons, and 57 neutrons.
I believe it is C.
Considering it is the only one that can be considered toxic”
