<h2>Answer </h2>

Number of molecules:  8.089×1022 molecules

<u>Explanation</u>

The formula for this question is

Number of molecules

= Number of moles × 6.02x1023

Since,  

the number of moles = given mass/formula mass

Here,  

Formula mass of sucrose= 342.3 g/mol  

Given mass= 46g  

Therefore,  

The number of molecules = given mass×6.02×1023/        

Formula mass  

=46×6.02×1023/342.3  

=8.089×1022 molecules.

How many atoms are there in 10.2 moles of Phosphorous?​
nikdorinn [45]

There are 2.06 x 10²⁴ atoms

<h3>Further explanation </h3>

The mole is the number of particles (atoms, molecules, ions)contained in a substance

1 mol = 6.02.10²³  particles

Moles can also be determined from the amount of substance mass and its molar mass

  • number of atoms :

\tt 10.2\times 6.02\times 106{23}=2.06\times 10^{24}

What is the molarity of a solution that contains 4.3 mol of acetic acid (C2H3O2) in 450. mL of solution?
lord [1]

Hey there !


Number of moles of solution: 4.3 moles

Volume in liters:

450.0 mL / 1000 => 0.45 L

Therefore:

Molarity = number of moles / volume of solution ( L)

Molarity = 4.3 / 0.45

=> 9.55 M

Hope that helps!
