Answer:
In this case, ethanol's molecular mass is 46 g/mol. This means that in 1 mol of ethanol, there are 46 g, thus the term molecular mass and molar mass are often used interchangeably. The same is true of a mole. A mole of anything is 6.022 x 1023 of that item
Explanation:
<span>Water is known as a polar molecule because the oxygen atom has a greater attraction for electrons than the hydrogen atom does. Oxygen is more electronegative than that of hydrogen creating a partial charges with the hydrogen and oxygen atoms. Also, the electrons of the covalent bond are not shared equally between the hydrogen and oxygen atoms making it polar.</span>
Explanation:
your heart is the main organ of the circulatory system
Mass of CH₄ is 10.591 g.
The molar mass is a crucial characteristic of the material that is independent of sample size. The coherent unit of molar mass in the International System of Units (SI) is kg/mol. However, molar masses are usually generally given in g/mol due to historical considerations.
A chemical compound's molar mass is calculated by dividing its mass by the number of moles of the substance that make up the sample.
Δg = 587.9 KJ
CH₄ Molar mass = 16.05 g/mol
mol CH₄ = Δg / ΔH°
= 587.9 / 890.3 KJ/ mol
= 0.6603 mol CH₄
Mass CH₄ = 0.6603 × 16.05 g/mol
= 10.591 g
Therefore, the mass of CH₄ is 10.591 g.
