342.14 g/mol
Molar mass of Al= 26.98
Molar mass of S=32.06
Molar mass of O=16.00
(26.98)2+(32.06+(16.00×4))3=342.14
Answer:
4 elements for C7H5(NO2)3
<span>Answer:
2Al(s) + 3Cl2(g) ---> 2AlCl3(s)
Always work in moles
moles = mass of substane / molar mass
2Al (s) + 3Cl (g) --> 2AlCl3 (s)
moles Al = 23.0 g / 26.98 g/mol
= 0.852 moles Al</span>
Thermal energy is heat and if you add heat to ice, it will melt and become a liquid (water)
