Question

Earth contains water and oxygen molecules. Each mass is given below. Which has the greater mass? Explain how you know.

water = 2.99 × 10-26 kg

oxygen = 2.66 × 10-26 kg

Answer 1

The water molecule has the greater mass because 2.99 is greater than 2.66. After comparing the exponents, which are the same, the coefficients are compared to determine the molecule with the greater mass.

Explanation:

Answer 2

We have that water has the greater mass because

`2.99 x 10{-26} kg > 2.66 x 10{-26}`

From the question we are told that

water = 2.99 × 10-26 kg

oxygen = 2.66 × 10-26 kg

Generally the equation for the elements mass is mathematically given as

water = 2.99 x 10{-26} kg

oxygen = 2.66 x 10{-26} kg

Therefore haven accessed the two mass we conclude

water is greater than oxygen

Because

`2.99 x 10{-26} kg > 2.66 x 10{-26}`
