Answer:
The answer to your question is Cm = 2.093 J/kg°C
Explanation:
Data
mass metal = mass of water
Δ water = 5°
Δ metal = 10°
Cm = ?
Cw = 4.186 J/Kg°C
Formula
for metal for water
mCmΔTm = mCwΔTw
Cancel mass of metal
Cm ΔTm = CwΔTw
solve for Cm
Cm = (CwΔTw) / ΔTm
Substitution
Cm = (4.186 x 5) / 10
Simplification
Cm = 20.93 / 10
Result
Cm = 2.093 J/kg°C

i do not understand what you're saying
Answer:
4.81×10⁻⁴ g K
Explanation:
Convert atoms to moles:
7.40×10¹⁸ atoms K × (1 mol K / 6.02×10²³ atoms) = 1.23×10⁻⁵ mol K
Convert moles to mass:
1.23×10⁻⁵ mol K × (39.1 g K / mol K) = 4.81×10⁻⁴ g K
atoms = smallest unit of an element
elements = contain only one type of atom
compounds = two or more elements that are chemically bound together
molecules = a group of atoms bonded together
Sorry I need the points!!
