If this cup of iced tea sits for a while on your kitchen table what will happen to its thermal energy

1 answer:

Alexus [3.1K]4 years ago

Because the tea is iced, it would be lower than room temp, meaning it would absorb thermal energy until it was the same temp as room temp, because thermal energy always goes where it is less concentrated until equilibrium has been reached.

How many silver atoms are there in 3.78g of silver?

oksian1 [2.3K]

2.1 x 10²²atoms

Explanation:

Given parameters:

Mass of silver = 3.78g

Unknown:

Number of atoms of silver = ?

Solution:

To solve this problem, we first find the number of moles of the silver from the given mass.

Number of moles = $\frac{Mass}{Molar mass}$

Molar mass of Ag = 108g/mole

Number of moles = $\frac{3.78}{108}$ = 0.035mole

Now;

A mole of any substance contains 6.02 x 10²³ atoms

0.035 moles of Ag will contain 0.035 x 6.02 x 10²³ = 2.1 x 10²²atoms
