The speed of the wave would be 718.21 feet /second if a wave going if it travels a distance of one mile in 7.35 seconds.

<h3>What is speed?</h3>

The total distance covered by any object per unit of time is known as speed. It depends only on the magnitude of the moving object.

As given in the problem we have to find out how many feet per second is a wave going if it travels a distance of one mile in 7.35 seconds.

1 mile = 1609 meters

1 meters = 3.28084 feets

1609 meters = 1609 ×3.28084 feets

= 5278.87 feets

As given if the wave travels a distance of one mile in 7.35 seconds.

then the wave would travel at 5278.87 feet in 7.35 seconds.

speed of the wave = 5278.87 /7.35

= 718.21 feet /second

Thus, the speed of the wave would be 718.21 feet /second

How many moles of oxygen are in 1 mole of fe(no3)3?

Naddika [18.5K]

One mole of Fe(NO3)3, or iron(III) nitrate, has three moles of nitrate molecules, which have three moles of oxygen atoms each. We can show this mathematically:
1 mole Fe(NO3)3 * (3 moles NO3)/(1 mole Fe(NO3)3) = 3 moles NO3
3 moles NO3 * (3 moles Oxygen)/(1 mole NO3) = 9 moles Oxygen
9 moles of Oxygen in one mole Fe(NO3)3

<h3>Explanation:</h3>

<u>Step 1: Define</u>

[Given] 0.456 g H₂O (water)

<u>Step 2: Identify Conversions</u>

[PT] Molar Mass of H - 1.01 g/mol

[PT] Molar Mass of O - 16.00 g/mol

Molar Mass of H₂O - 2(1.01) + 16.00 = 18.02 g/mol

<u>Step 3: Convert</u>

[DA] Set up: $\displaystyle 0.456 \ g \ H_2O(\frac{1 \ mol \ H_2O}{18.02 \ g \ H_2O})$
