Answer: The total pressure of the container is 231.97 kPa.
Explanation:
Given: ,
,
Total pressure is the sum of pressure of each component of the gas present in a vessel or container.
Hence, total pressure of the container is calculated as follows.
Thus, we can conclude that the total pressure of the container is 231.97 kPa.

i think the answer is C because it take a Molecular form so im certain the correct answer is c
10.045830 × atoms of scandium are in 75.0 g.
<h3>What are moles?</h3>
A mole is defined as 6.02214076 × of some chemical unit, be it atoms, molecules, ions, or others. The mole is a convenient unit to use because of the great number of atoms, molecules, or others in any substance.
Given data:
Mass of scandium = 7
Molar mass of scandium=44.96 g/mol
Moles =1.66814 moles
Number of atom= 1.66814 moles x 6.02214076 ×
Hence, 10.045830 × atoms of scandium are in 75.0 g.
