Answer to Question #179338 in Chemistry for grace

Question

use the formula q=mc t to calculate the number of joules gained by the 50 mL sample of water

Answer 1

q=m x C x deltaT

density = m / V

density (H₂O) = 1 g/ml

m (H₂O) = 50 x 1 = 50 g = 0.05 kg

C (H₂O) = 4182 J/kg°C

deltaT = 1°C

q = 0.05 x 4182 x 1 = 209,1 J
