Chapter 2: Q. 2.17 (page 31)

Identify the numbers in each of the following statements as measured or exact:

(a) A patient has a mass of 67.5kg.

(b) A patient is given 2tablets of medication.

(c) In the metric system, 1Lis equal to 1000ml.

(d) The distance from Denver ,Colorado, to Houston, Texas, is 1720km.

Short Answer

Expert verified

(a) Measured , as it is mass.

(b) Exact, as it is tablets doses.

(c) Exact, as it is universally accepted.

(d) Measured, as distance is always measured.

Step by step solution

01

Part(a) Step1 : Given information.

We have been given mass of patient =67.5kg.

We need to state whether this statement is exact or measured.

02

Part(a) Step2 : Simplify.

Measured. Since it is mass so it is obvious that it will be measured. Mass can vary from person to person ,therefore it is measured.

03

Part(b) Step1 : Given information.

We have been given that, a patient is given two tablets of medication.

We need to state whether this statement is exact or measured.

04

Part(b) Step 2: Simplify.

Exact. It is recommendation by doctor for use of tablets, therefore it is exact. It denotes the number of doses to be taken so, it can not be measured.

05

Part(c) Step1 : Given information.

We have been given that in metric system 1Lis equals to 1000mL.

We need to state whether this statement is exact or measured.

06

Part(c) Step2: Simplify.

Exact. Since it is universal, therefore it is exact. In metric system it has been already accepted and used globally ,hence it is always exact.

07

Part(d) Step1: Given information.

We have been given the distance between different states .

We need to state whether this statement is exact or measured.

08

Part(d) Step2 : Simplify.

Measured. The distance between different states is measured .

Distance is fundamental quantity ,hence it is measured .
