Answer:

The final temperature of the mixture is closest to 30ºC

Explanation:

<u>Step 1:</u> 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
