6.0 g of glass heated from 17c to 47c.how much energy was used to heat the glass?(specific heat capacity of glass is 0.664 j/g

Question

I need help

Answer 1

I assume you meant to say that the specific heat is 0.664 J/(g°C).  Specific heat must have units of energy/(mass x temperature).

 

Q = mcΔT = (6.0 g) [0.664 J/(g°C)] (47°C - 17°C) = ? J

 

Just evaluate the expression above.
