Question

multiply or divide the following measurements. be sure each answer you enter 992.1 mol ÷ 0.56 l = □ \frac{\text{mol}}{\text{l}} 0.93 \frac{\text{mol}}{\text{l}} × 0.85 l = □ \text{mol} 0.93 \frac{\text{g}}{\text{ml}} × 3.725 \text{ml} = □ \text{g}

Explanation:

First Calculation: \( 992.1 \, \text{mol} \div 0.56 \, \text{L} \)

Step1: Perform the division

We need to divide \( 992.1 \) by \( 0.56 \).
\( 992.1\div0.56=\frac{992.1}{0.56}\approx1771.61 \) (rounded to two decimal places)

Step1: Multiply the numbers and cancel units

Multiply \( 0.93 \) and \( 0.85 \), and the \( \text{L} \) units cancel out.
\( 0.93\times0.85 = 0.7905 \)

Step1: Multiply the numbers and cancel units

Multiply \( 0.93 \) and \( 3.725 \), and the \( \text{mL} \) units cancel out.
\( 0.93\times3.725= 3.46425 \)

Answer:

(First):
\( 1771.61 \frac{\text{mol}}{\text{L}} \)

Second Calculation: \( 0.93 \frac{\text{mol}}{\text{L}} \times 0.85 \, \text{L} \)
