Answer:49.3
Explanation:4.1j/g c * 25g * (t2-45c)=455j
T2-45c = 455j/4.1j/g c * 25g
455/104.6
45+4.3= 49.3 celsius
Answer:one atom
Explanation:
The carbon symbol is C so only one
Calcium has 1 atom
Oxygen has 3 atoms
Aluminum Al2713 has an atomic molar mass of 27 grams per mole.
Al has 13 protons (hence number 13) and it most common isotope 14 neutrons for a total mass of 27 amu. ( The 13 electrons add no measurable mass to the atom)
Take the grams and divide by the molar mass
= 2 moles
