(a) Interpretation: The minimum weight of the sample for relative error due to 0.5 mg loss to be less than 0.1% needs to be determined. Concept introduction: The minimum weight is calculated by the relative error formula which is given below- E r = E m − E t E t × 100 Here, E r = relative error E m = measured value E t = true value

Solutions

Chapter A1, Problem A1.4QAP
Interpretation Introduction

(a)

Interpretation:

The minimum weight of the sample for relative error due to 0.5 mg loss to be less than 0.1% needs to be determined.

Concept introduction:

The minimum weight is calculated by the relative error formula which is given below-

Er=EmEtEt×100

Here,

Er = relative error

Em = measured value

Et = true value

Interpretation Introduction

(b)

Interpretation:

The minimum weight of the sample for relative error due to 0.5 mg loss to be less than 0.5 % needs to be determined.

Concept introduction:

The minimum weight is calculated by the relative error formula which is given below-

Er=EmEtEt×100

Here,

Er = relative error

Em = measured value

Et = true value

Interpretation Introduction

(c)

Interpretation:

The minimum weight of the sample for relative error due to 0.5 mg loss to be less than 0.8 % needs to be determined.

Concept introduction:

The minimum weight is calculated by the relative error formula which is given below-

Er=EmEtEt×100

Here,

Er = relative error

Em = measured value

Et = true value

Interpretation Introduction

(d)

Interpretation:

The minimum weight of the sample for relative error due to 0.5 mg loss to be less than 1.2 % needs to be determined.

Concept introduction:

The minimum weight is calculated by the relative error formula which is given below-

Er=EmEtEt×100

Here,

Er = relative error

Em = measured value

Et = true value
