<u>Answer:</u> The volume of oxygen gas is 0.332dm^3

<u>Explanation:</u>

To calculate the volume of the gas, we use the equation given by ideal gas equation:

PV=nRT

where,

P = pressure of the gas = 5 MPa = 5000 kPa   (Conversion factor: 1 MPa = 1000 kPa)

V = Volume of gas = 3.34 L

n = number of moles of oxygen gas = 1 mole

R = Gas constant = 8.31dm^3\text{ kPa }mol^{-1}K^{-1}

T = Temperature of the gas = 200 K

Putting values in above equation, we get:

5000kPa\times V=1mol\times 8.31dm^3\text{ kPa }mol^{-1}K^{-1}\times 200K\\\\V=0.332dm^3

Hence, the volume of oxygen gas is 0.332dm^3

Using the VSEPR theory , what would the representation mean A central atom with 2 connected atoms atom with I lone pair of Jone
VLD [36.1K]

Answer:

The molecule has a bent geometry

Explanation:

Let us look again at the principles of VSEPR theory. The shape of a molecule depends on the number of electron pairs that surround the valence shell of the central atom in the molecule.

Lone pairs distort the molecular geometry away from what is expected on the basis of VSEPR theory.

The molecule described in the question has the form AEX2. Two substituents and one lone pair form three electron domains around the central atom. The expected geometry is trigonal planar but the observed molecular geometry is bent because of the lone pairs present.

How many moles are there in 990 grams of sugar, C12H22011? (Sig Figs, do not
Nitella [24]

Answer:

Number of moles = 2.89 mol

Explanation:

Given data:

Number of moles of sugar  = ?

Mass of sugar = 990 g

Solution:

Formula:

Number of moles = mass/molar mass

Molar mass of C₁₂H₂₂O₁₁:

12× 12 + 22×1.008 + 16×11 = 342.2 g/mol

Number of moles = 990 g / 342.2 g/mol

Number of moles = 2.89 mol
