Answer:
The final temperature of the mixture is closest to 30ºC
Explanation:
Step 1: Data given
Volume of sample 1 = 30 mL ≈ 30 grams
Temperature of sample 1 = 10 °C
Volume of sample 2 = 50 mL ≈ 50 grams
Temperature of sample 2 = 50 °C
Step 2: Calculate the final temperature
T(final) = (30 g * 10 °C + 50 g * 50 °C) / (50 g + 30 g)
T(final) = (300 + 2500)/80
T(final) = 35 °C
The final temperature of the mixture is closest to30ºC
