Problem 104a

Chapter 1, Problem 104a

Which is larger in each pair, and by approximately how much? (a) A liter or a quart

Verified step by step guidance

Step 1: Understand the units involved. A liter is a metric unit of volume, while a quart is an imperial unit of volume.

Step 2: Recall the conversion factor between liters and quarts. 1 liter is approximately equal to 1.0567 quarts.

Step 3: Compare the two units using the conversion factor. Since 1 liter is equal to 1.0567 quarts, a liter is larger than a quart.

Step 4: Calculate the difference in volume. Subtract 1 quart from 1.0567 quarts to find the approximate difference.

Step 5: Express the difference in terms of quarts to understand how much larger a liter is compared to a quart.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Volume Units

Volume is a measure of the three-dimensional space an object occupies. Common units for measuring volume include liters and quarts. Understanding the relationship between these units is essential for comparing their sizes.

Liter vs. Quart

A liter is a metric unit of volume equivalent to 1,000 cubic centimeters, while a quart is an imperial unit equal to approximately 0.946 liters. This means that a liter is slightly larger than a quart, specifically by about 0.054 liters or 54 milliliters.

Unit Conversion

Unit conversion involves changing a quantity expressed in one unit to another unit. It is crucial for accurately comparing different measurement systems, such as metric and imperial. Familiarity with conversion factors allows for precise calculations and comparisons.

Textbook Question

Administration of digitalis, a drug used to control atrial fibrilla-tion in heart patients, must be carefully controlled because even a modest overdose can be fatal. To take differences between patients into account, drug dosages are prescribed in terms of mg/kg body weight. Thus, a child and an adult differ greatly in weight, but both receive the same dosage per kilogram of body weight. At a dosage of 20 mg/kg body weight, how many mil-ligrams of digitalis should a 160 lb patient receive?
