Hey there!
1 mol is 6.022 x 10²³ formula units.
To find the amount of formula units in 5.81 mol of BaCl₂, we need to multiply the amount in 1 mol by 5.81.
5.81 x 6.022 x 10²³
35.0 x 10²³
3.40 x 10²⁴
There are 3.4 x 10²⁴ formula units in 5.81 mol BaCl₂.
Hope this helps!
Never true.
Accuracy is how close your answer is to the one you were supposed to get.
Precision is how repeatable the answer you got was.
The Earth, Mars or Jupiter should be denser than the Sun. Density is defined by mass and volume — components of object or matter. Although the sun is huge, it’s component is made up of mostly gas (hydrogen and helium). While Earth, though smaller than the Sun, contains heavier elements such as iron, sulfur, rocks, sediments, granite, basalt and water. Mars (composed of rocks and nutrients) and Jupiter (contains gases and compounds) as well are denser when compared to the Sun’s density. Referencing to our basic understanding of matter: solid and liquid should be heavier than gas.
