Answer:

7.87 x 10²³ atoms

Explanation:

The number of LiCl units is related to moles using Avogadro's constant (6.022 × 10²³ mol⁻¹):

(0.654 mol)(6.022 × 10²³ mol⁻¹) = 3.93 x 10²³ LiCl

One LiCl unit is composed of two atoms, one Li atom and one Cl atom, so the amount is multiplied by 2:

(3.93 x 10²³)(2) = 7.87 x 10²³ atoms

The specific heat of water is 4.18 J/(g⋅∘<br> c. Calculate the molar heat capacity of water.
Xelga [282]

We are given that the specific heat of water is 4.18 J / g °C. We know that the molar mass of water is 18.02 g/mol, therefore the molar heat capacity is:

 

molar heat capacity = (4.18 J / g °C) * 18.02 g / mol

<span>molar heat capacity = 75.32 J / mol °C</span>
