Molar mass RbMnO₄ = 204.40 g/mol
1 mole ---------- 204.40 g
7.88 mole ------ ?
mass = 7.88 * 204.40 / 1
mass = 1610.672 g
hope this helps!
Answer:A feedback loop is a process in which the outputs of a system are circled back and used as inputs. In business, this refers to the process of using customer or employee feedback (the outputs of a service or product), to create a better product or workplace

a) Hydrogen is the chemical element with the symbol H; is the lightest element in the periodic table.
b) Water: It is a substance whose molecule is composed of two atoms of hydrogen and one of oxygen.
⇒ molecular formula: H2O
c) gold: is the chemical element with the symbol Au. It is a very dense, soft and intense yellow metal.
d) sugar: it is a compound whose chemical formula is C12H22O11
Answer:
3.34×10³⁰ molecules of C₉H₈O₄
Explanation:
Let's determine the molar mass of aspirin:
C₉H₈O₄ → 12 g/mol . 9 + 1g/mol . 8 + 16g/mol . 4 = 180 g/mol
Let's convert the mass from g to mg → 180 g . 1000 mg/1g = 180000 mg
= 1.8×10⁵ mg
Now, we make a rule of three:
In 1.8×10⁵ mg of aspirin (1 mol) we have 6.02×10²³ molecules
In 100 mg of aspirin, we may have ( 100 . 6.02×10³) / 1.8×10⁵ = 3.34×10³⁰ molecules
Km is a bigger (longer) distance
