How many moles are there in 8.50 X 1024 molecules of sodium sulfate, Na2SO3?

Chemistry
1 answer:
il63 [147K]2 years ago
3 0

Answer:

<h2>14.12 moles</h2>

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

n =  \frac{N}{L} \\

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

n =  \frac{8.50 \times  {10}^{24} }{6.02 \times  {10}^{23} }  \\  = 14.119601...

We have the final answer as

<h3>14.12 moles</h3>

Hope this helps you

What would be the volume of 0.500 mole of an ideal gas at a temperature of 273.15 Kelvins and 1 atm?
uysha [10]

Answer:

V = 11.21 L

Explanation:

Given data:

Volume of helium = ?

Number of moles = 0.500 mol

Temperature = 273.15 K

Pressure of gas = 1 atm

Solution:

Formula:

PV = nRT

R = general gas constant = 0.0821 atm.L/ mol.K

V = nRT/P

V = 0.500 mol ×  0.0821 atm.L/ mol.K  × 273.15 K / 1 atm

V = 11.21 L / 1

V = 11.21 L

Which polyatomic ion is found in the compound represented by the formula NaHCO3?
stiv31 [10]

Answer: The correct option is 2.

Explanation: Polyatomic ions are defined as the ions in which two or more elements are covalently bonded to act as a single unit. They always carry some charge.

Examples of polyatomic ions are: OH^- known as hydroxide ion, SO_4^{2-} known as sulfate ion

We are given a compound NaHCO_3 having 2 ions which are Na^+ and HCO_3^-. these ions are named as sodium ions and hydrogen carbonate ions.

Therefore, the correct option is 2.

SashulF [63]

88.98 %

The Balance Chemical Equation is as follow,

                                  2 HCl + Pb(NO₃)₂     →    2 HNO₃ + PbCl₂

According to equation,

          331.2 g (1 mole) Pb(NO₃)₂ produces  =  278.1 g (1 mole) PbCl₂

So,

                 870 g of Pb(NO₃)₂ will produce  =  X g of PbCl₂

Solving for X,

                     X  =  (870 g × 278.1 g) ÷ 331.2 g

                     X  =  730.5 g of PbCl₂

Therefore,

               Theoretical Yield =  730.5 g

Also as given,

                Actual Yield =  650 g

So using following formula for percentage yield,

                        %age Yield  =  (Actual Yield / Theoretical Yield) × 100

Putting values,

                        %age Yield  =  (650 g / 730.5 g) × 100

                        %age Yield  =  88.98 %

Brianliest please and thank you.

What causes an earthquake?
ElenaW [278]

Answer:

Earthquakes are usually caused when rock underground suddenly breaks along a fault. This sudden release of energy causes seismic waves to be released, causing the ground to shake.

Earthquakes are caused by movement in the tectonic plates(known as plate tectonics).

This usually happens in plate boundaries(where one plate meets another), due to the pressure that builds up as the plates try to move, since tectonic plates are constantly moving
