Answer: 0.156 mol
Explanation:
To find the moles of 17.2 g K₂S, we need to know the molar mass to convert.
Hydrogen H weight: 81
Non-metal
Hydrogen is the simplest element; an atom consists of only one proton and one electron. It is also the most plentiful element in the universe. Despite its simplicity and abundance, hydrogen doesn't occur naturally as a gas on the Earth--it is always combined with other elements.
period 1 group 1
Hydrogen is easily the most abundant element in the universe. It is found in the sun and most of the stars, and the planet Jupiter is composed mostly of hydrogen. On Earth, hydrogen is found in the greatest quantities as water.

C. Parents can pass on useful traits to offspring
Explanation:
The Volume and the density of the box are 480 in³, 7865.81 cm³, 0.127 g/mL
<h3>What is volume?</h3>
This is the measure of the capacity of substance an object can hold.
To calculate the volume of the box, we use the formula below
Formula:
- V = LWH................. Equation 1
Where:
- V = Volume of the box
- L = Length of the box
- W = Width of the box
- H = Height of the box.
From the question,
Given:
- L = 10 inches
- W = 8 inches
- H = 6 inches.
Substitute these values into equation 1
We convert the volume from cubic inches to cubic centimeters using the expression below.
- V = (480×16.3871) = 7865.81 cm³
<h3>What is density?</h3>
Density can be defined as the ratio of the mass and volume of a body.
To calculate the density of the box, we use the formula below.
- D = m/V.................. Equation 2
From the question,
Given:
- m = 1 kg = 1000 g
- V = 480 in³ = (480×16.3871) milliliter = 7865.81 mL
Substitute these values into equation 2
- D = 1000/7865.81
- D = 0.127 g/mL
Hence, The Volume and the density of the box are 480 in³, 7865.81 cm³, 0.127 g/mL.
