question 7 (1 point)
given that the density of acetic anhydride is 1.082 g/ml, what is the mass of 4.41
ml of acetic anhydride? report answers with correct significant figures. do not
include the units in your response.
your answer:
answer

Explanation:

Step1: Recall the density formula

The formula for density is \(
ho=\frac{m}{V} \), where \(
ho \) is density, \( m \) is mass, and \( V \) is volume. Rearranging for mass gives \( m =
ho\times V \).

Step2: Substitute the given values

Given \(
ho = 1.082\space g/mL \) and \( V=4.41\space mL \), then \( m=(1.082)(4.41) \).

Step3: Determine significant figures

The density \( 1.082 \) has four significant figures and the volume \( 4.41 \) has three significant figures. When multiplying, the result should have the same number of significant figures as the least - precise measurement. So, the result should have three significant figures. Rounding \( 4.77162 \) to three significant figures gives \( 4.77 \).

Answer:

4.77
