<span>Pentan-1-ol. 'Pentan' because it has a chain of 5 carbons. 'ol' because it has an alcohol group at the end (-OH), and the 1 represents the position of the alcohol group on the cardon chain. Though it is not an element. It is a compound which contains the elements Carbon, Hydrogen and Oxygen.

Temka [501]

Answer: 62.173%

explanation:

equation for percentage mass of an element in a compound = (Mass of element in compound / mass of the whole compound ) × 100%

% mass = (46.63÷75.00) × 100

= 0.62173 × 100

= 62.173%

If 75 g of oxygen react how many grams of aluminum are required
daser333 [38]

Answer:

84.24 g

Explanation:

Given data:

Mass of oxygen = 75 g

Mass of Al required to react = ?

Solution:

Chemical equation:

4Al + 3O₂     →   2Al₂O₃

Number of moles of oxygen:

Number of moles = mass/ molar mass

Number of moles = 75 g/ 32 g/mol

Number of moles = 2.34 mol

Now we will compare the moles of oxygen with Al.

                         O₂         :          Al

                          3          :             4

                       2.34        :         4/3×2.34 = 3.12 mol

Mass of Al required:

Mass = number of moles × molar mass

Mass = 3.12 mol × 27 g/mol

Mass = 84.24 g
