perform the calculation. 109 j ÷ (20.0 g × 2.51 j/g°c) write your answer with the correct number of significant figures. round if necessary.
Answer
Explanation:
Step1: Calculate the denominator
First, calculate $20.0\ g\times2.51\ J/g^{\circ}C$. $20.0\times2.51 = 50.2\ J/^{\circ}C$
Step2: Perform the division
Then, divide the numerator by the result of step 1. $109\ J\div(50.2\ J/^{\circ}C)=\frac{109}{50.2}^{\circ}C\approx 2.17^{\circ}C$
Answer:
$2.17^{\circ}C$
