a shrew, a mammal with the fastest metabolism, has a mass of only 0.004 kg what is its mass in grams

The mass of the shrew is 4 grams

Step-by-step explanation:

1. Let's review the information provided to us to answer the question correctly:

Mass of a shrew = 0.004 kilograms

2. What is the mass of the shrew in grams?

Let's convert the mass of the shrew from kilograms to grams, this way:

1 kilogram = 10³ grams

1 kilograms = 1,000 grams

Now replacing with the real values, we have:

0.004 kilograms = 0.004 * 1,000 grams

0.004 kilograms = 4 grams

The mass of the shrew is 4 grams
