A block of aluminum occupies a volume of 15ml and weighs 40.5 g, what it its density?

san4es73 [151]

<h2>Answer:3 $gmL^{-1}$ </h2>

Explanation:

Let $v$ be the volume of the given material.

Let $m$ be the mass of the material.

Let $d$ be the density of the material.

Density of a material is defined as the ratio of its mass to its volume.

$d=\frac{m}{v}$

Given,

$m=45g\\v=15ml$

So, $d=\frac{45}{15}=3gmL^{-1}$

What features do all the resonance forms of a molecule or ion have in common?

NeX [460]

Answer/Explanation:

Things that will vary include the distribution of electrons between atoms, lone pairs, and bonds, the number of single vs double or triple bonds, and the formal charges on atoms in the structure.

All resonance forms of the same molecule or ion must have the same number of atoms, connected in the same way, and the same number of total electrons.

Subtracting atomic number from atomic mass will give the number of

faltersainse [42]

Answer:

Explanation:

If we subtract the atomic number from the atomic mass: atomic mass - atomic number = number of protons + number of neutrons - number of protons. Thus we get the number of neutrons present in an atom when we subtract the atomic number from the atomic mass.

A 3.0 L cointainer contains 4 mol He, 2 mol Ne,and 1 mol Ar. What is the mole fraction of neon gas? What is the partial pressure

CaHeK987 [17]

Answer:

Partial pressure of Ne = 1.43 atm

Explanation:

Step 1: Data given

Volume = 3.0 L

Number of moles He = 4 moles

Number of moles Ne = 2 moles

Number of moles Ar = 1 mol

Total pressure = 5 atm

Step 2: Calculate total moles

Total moles = 4 moles + 2 moles + 1 mol

Total moles = 7 moles

Step 3: Calculate the mol ratio

Mol ratio = moles / total mol

Mol ratio He = 4 moles / 7 moles = 0.571

Mol ratio Ne = 2 moles / 7 moles = 0.286

Mol ratio Ar = 1 mol / 7 moles = 0.143 moles

Ste p4: Calculate partial pressure

PArtial pressure = mol ratio * total pressure

Partial pressure of Ne = mol ratio Ne * total pressure

Partial pressure of Ne = 0.286 * 5 atm

Partial pressure of Ne = 1.43 atm
