Mol = # atoms ÷ Avagadaro's number (6.02×10^23)

mol = 2.4×10^24 ÷ 6.02×10^23
mol = 3.986 mol

Answer:

n_{He}=3.99molHe

Explanation:

Hello,

To compute the required moles, we consider the Avogadro's number relationship for 1 mole of atoms as shown below:

n_{He}=2.4x10^{24}atomsHe*\frac{1mol He}{6.022x10^{23}atoms He}\\n_{He}=3.99molHe

Best regards.

Plz help ASAP. thx for you answers​ ALGEBRA 2 sorry
iren [92.7K]

So, the answer to 27.) would be <em>2x.</em> Both 6x and 2x can be divided by 2x, but they can't go any higher without the end-answer becoming a fraction. As such, 2x is the greatest common factor.

For 28.), x and x^2 can't be like terms, since like terms have the same variable and exponent :)

Hope I could help!

A chemical formula shows the kinds and numbers of _____ in the smallest representative unit of a substance.
Firdavs [7]

A chemical formula shows the kinds and numbers of <u>atoms</u> in the smallest representative unit of a substance.

<u>Explanation:</u>

In chemistry, a  formula unit is the empirical formula of "ionic or covalent network solid compound" that is used as an independent entity for "stoichiometric calculations". This formula is a representation of a molecule that uses chemical symbols.

The unit is the lowest whole number ratio of ions represented in an ionic compound. It gives the numbers of atoms representing the "smallest representative" unit of a substance. The number of atoms also tells us about the chemical and physical properties of the compound formed.
