Question

1. 0.25 g is equivalent to

a. 250 kg.
b. 250 mg.
c. 0.025 mg.
d. 0.025 kg.

Explanation:

Step1: Recall unit conversion for grams to milligrams

We know that \(1\ \text{g} = 1000\ \text{mg}\). So to convert grams to milligrams, we multiply the number of grams by 1000.

Step2: Convert 0.25 g to mg

Using the conversion factor, \(0.25\ \text{g}\times1000\ \frac{\text{mg}}{\text{g}} = 250\ \text{mg}\).
Let's check other options:

• Option a: \(1\ \text{kg}=1000\ \text{g}\), so \(0.25\ \text{g}=\frac{0.25}{1000}\ \text{kg} = 0.00025\ \text{kg}

eq250\ \text{kg}\).

• Option c: \(1\ \text{g} = 1000\ \text{mg}\), so \(0.25\ \text{g}=250\ \text{mg}

eq0.025\ \text{mg}\).

• Option d: As calculated above, \(0.25\ \text{g}=0.00025\ \text{kg}

eq0.025\ \text{kg}\).

Answer:

b. 250 mg
