Iam sorry I don't know but why Iam messaging iss because when more people message it usually appears to more people so someone else will be able to help you:)
It helps to map out how you will navigate through your unit analysis problem before setting it up.
You are given moles and need grams. What can be used as a conversion factor from moles to grams? Molar mass. We are working with aluminum, so we will need the molar mass of aluminum. My Periodic Table tells me the molar mass of aluminum is approximately 27 g/mol. Now we are ready to set up the unit analysis.

Moles must go on the bottom so that they cancel. Notice how our number of significant figures is 2, so the answer must round to 16 g Al.

Answer:</h3>
16 grams
Answer : The correct option is, Subscript numbers tell us how many of the element to their upper-left there are in the molecule.
Explanation :
Subscript number : It indicates that the total number of atoms of an element present in a molecule.
While witting a chemical formula, first we have to write the symbol of an element and then write the number in the bottom of the symbol.
For example :
is the chemical formula of the glucose molecule. The glucose molecule is made up of six carbon atoms, twelve hydrogen atoms and 6 oxygen atoms.
The number 6 of carbon atom is written after and in the bottom (lower-right) of the symbol of carbon element (C). Similarly, the number 12 is written lower-right of the symbol of hydrogen element (H) and the number 6 is written lower-right of the symbol of oxygen element (O).
Therefore, the subscript numbers tell us how many of the element to their upper-left there are in the molecule.
Answer:
For chemical reactions involving gases, gas volume measurements provide a convenient means of determining stoichiometric relationships.

Answer:
Cyclothymic Disorder
Explanation:
Cyclothymic disorder is a rare type of mood disorder whose symptoms resemble that of bipolar disorder. Although, the symptoms are manifested in a milder manner when compared with those of bipolar disorder.
The mood shifts in cyclothymic disorder are not as extreme as with Bipolar disorder.
The normal moods in cyclothymic disorder can last for a longer time than in bipolar disorder.
Although, the mood swings in cyclothymic disorder are more frequent than in bipolar disorder.
The true causes of cyclothymic disorder are not specifically known but bipolar disorder & cyclothymic can both occur in the same family suggesting that they may share similar causes.
