Question 15

2 Points

How much energy is required to heat 44.72 g of H2O from 10.00 oC to 37.50 oC? (Heat capacity of liquid H2O = 75.37 J mol-1 K-1) (type in the numeric value in Joules - give your answer to 4 significant figures, do not include the units in your answer only the number, do not use scientific notation, do not include comma's) BLANK-1

Answer #1

Energy = nCmAT [n-moles of tho] - 44.729 x 75.37 I X (37.50-10:00) K 18 g/mol mol-k = 5149.44 J = 5149temperature difference is same in °C as well as in Kelvin so do not bother to convert the unit.
