A 5.00 g sample of aluminum pellets (specific heat capacity = 0.89 J/°C•9) and a 10.00 g sample of iron pellets (specific heat capacity = 0.45 J/°C-g) are heated to 100.0°C. The mixture of hot iron and aluminum is then dropped into 91.5g of water at 20.8°C. Calculate the final temperature of the metal and water mixture, assuming no heat loss to the surroundings. Respond with the correct number of signficant figures in scientific notation. (Use E notation and only 1 digit before decimal, for example, 2.5E5 for 2.5 times 10 to the power of 5)Respond with the correct number of significant figures in scientific notation (Use E notation and only 1 digit before decimal e.g. 2.5E5 for 2.5 x 10°)
