The function of mordant in the gram staining is to expose grams positive cell to the decolorizer which dissolves the lipids in the cell wall thus allowing the crystals violent-iodine to leach out of the cell. This facilitate the cell subsequently be stained by with safranin.
<h3><u>Answer;</u></h3>
= 20,280.25 g or 20.28 Kg
<h3><u>Explanation;</u></h3>
Number of moles, n = Molarity × Volume
Molarity = 6.81 M
Volume = 8.7 L
Number of moles = 6.81 × 8.7
= 59.247 moles
Mass = Moles × Molar mass
= 59.247 × 34.2 g/mol
= 20,280.25 or
= 20.28 Kg
Answer:
19.32 g/cm³
Explanation:
The density will remain the same no matter how many times you cut the gold. The density is g/cm³ or g/mL. Density is essentially how many grams 1 mL of a compound weighs.
Answer: 2. Heat flows from faster molecules to slower molecules when they collide.
