Answer:

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

$volume = \frac{mass}{density} \\$

From the question we have

$volume = \frac{935}{7.8} \\ = 119.871794...$

We have the final answer as

<h3>119.87 cm³ to two decimal places</h3>

Hope this helps you

Hey there!:

The 1s, 2s and 2p subshells are completely filled (a maximum of two electrons go into the 1s subshell and a maximum of two electrons go into the 2s subshell. The 2p subshell includes 3 orbitals, with 2 electrons maximum per orbital). The 3s subshell has only one of a maximum of two electrons.

Hope that helps!

7. I have 2.50 x 1023 atoms of titanium. How many moles of titanium dol<br> have?

algol13

Answer:

0.42mole

Explanation:

Given parameters:

Number of atoms of titanium = 2.5 x 10²³atoms

Unknown:

Number of moles = ?

Solution:

To solve this problem, we must understand that a mole of any substance contains the Avogadro's number of particles.

6.02 x 10²³ atoms makes up 1 mole of an atom

2.5 x 10²³ atoms will contain $\frac{2.5 x 10^{23} }{6.02 x 10^{23} }$ = 0.42mole
