1.65 x 10^24  molecules in 100 grams of HCL

because HCL is 36.461 grams/mol

and there are 6.02 x 10^23 molecules/ mol

if you did stochiometry this is what you will get 1.65 x 10^24

hope i helped

Calculate the amount of heat required to melt 2108 g of water. The enthalpy of fusion of water is ΔHfus=6.010 kJ/mol.
vesna_86 [32]

since the unit for the heat of fusion is kJ/mol, you're going to have to convert the grams into moles in order to cancel out the unit. After that, you can solve like normal.

Mehtyl alcohol is called wood spirit. Its molecular formula is CH3OH. Calculate the number of moles that would contain 2.5*10^21
Phoenix [80]

The 2.5 x 10²¹ molecules of CH₃OH have 0.00415 moles.

<h3>What is the mole concept?</h3>
  • The Mole concept is used to express the amount of substance conveniently.
  • A mole is defined as the amount of substance that contains exactly 6.022 x 10²³ elementary particles of the given substance. Here, elementary particles refer to atoms, molecules, or ions.
  • This fixed number  6.022 x 10²³ is known as Avogadro Number and is denoted by N_A
<h3>How to calculate the number of moles?</h3>

The number of moles is given by

n=\frac{m}{M}

When given mass = molar mass of a substance, then no of moles is equal to 1 which is equivalent to 6.022 x 10²³.

We also know,

1 mole has 6.022 x 10²³ molecules of CH₃OH

According to the mole concept,

6.022 x 10²³ molecules of CH₃OH is equal to 1 mole

2.5 x 10²¹molecules of CH₃OH is equal to \frac{2.5\times10^2^1}{6.022 \times 10^2^3} moles

Thus, 2.5 x 10²¹molecules of CH₃OH are equal to 4.15 x 10⁻³ moles or 0.00415 moles
