While camping up at Haloooo Mountain (5,500 feet above sea level), it generally takes Sandy about the same amount of time to boil water for her soup as it takes to make a sandwich. This week, Sandy is camping at a trail that is only about 200 feet above sea level. Sandy is very hungry and wants something to eat immediately. Should she make the soup or sandwich? Which would be ready more quickly and why?

Answer:
342.17 g/mol
Explanation:
Molecular formulas is the actual number of atoms of each element in the compound. Molecular mass is the sum of the mass of each element which is present in the molecular formula is multiplied by their subscript which appear in the molecular formula.
Given,
The formula is =
Mass from the formula = 2×Molar mass of Aluminium + 3×Molar mass of sulfur + 12×Molar mass of Oxygen
Molar mass of Aluminium = 27.00 g/mol
Molar mass of sulfur = 32.06 g/mol
Molar mass of Oxygen = 15.99 g/mol
So,
Mass from the formula = 2×27.00 + 3×32.06 + 12×15.99 g/mol ≅ 342.17 g/mol
The molar mass of is 342.17 g/mol. The correct answer is option C.
Molar mass is the mass of one mole of a substance. It is expressed in units of grams per mole (g/mol).
To calculate the molar mass of , we need to add up the atomic masses of all the atoms in one formula unit.
So, the molar mass of can be calculated as follows:
Molar mass = (2 × atomic mass of Al) + (3 × atomic mass of S) + (12 × atomic mass of O)
= (2 × 26.98 g/mol) + (3 × 32.07 g/mol) + (12 × 16.00 g/mol)
= 342.17 g/mol
Therefore, the answer is option C. 342.17 g/mol is the molar mass of .

Begin by balancing the equation:
2 Fe2O3 —> 4 Fe + 3 O2
Start your stoic:
(79.2g Fe2O3) <—- you start with what you have and always try to get rid of what unit you are at
Conversion to get rid of grams is
# grams over mole
^
This number comes from periodic table
Add whole mass of Fe2O3= 159.697g
(79.2g Fe2O3)(. mole. )
(159.697g)
Now get rid of moles, this is where you used the balanced numbers at the beginning
The number you are looking for goes on top—> (4 moles Fe)
(2 moles Fe2O3)
Last get mass of Fe alone and plug in to calc
Whole equation:
(79.2g)( moles)(4mFe)(55.85gFe)
(159.697)(2mole)(mole)
79.2 divides by 159.697 multiplied by 4 divided by 2 multipled by 55.85 equals 55.396406 rounded to:
55.4 g Fe
Answer: The mass of iron present is 55.40 g
Explanation:
We know that:
Molar mass of iron (III) oxide = 159.7 g/mol
Molar mass of iron = 55.85 g/mol
We are given:
Mass of iron (III) oxide = 79.2 g
To calculate the mass of iron in given amount of iron (III) oxide, we use unitary method:
In 159.7 grams of iron (III) oxide, the mass of iron is (2 × 55.85) = 111.7 g
So, in 79.2 grams of iron (III) oxide, the mass of iron will be =
Hence, the mass of iron present is 55.40 g
