Answer:

Cell division

Explanation:

  • Cell division helps maintain homeostasis in living things since it creates new cells which can be used for growth and repair.
  • <em><u>Cell division occurs into two types, meiosis and mitosis . During mitosis, the cell creates two identical daughter cells that are identical to the parent cell, in terms of the number of chromosomes.</u></em>
  • These new cells are necessary to replace old cells that die in the organism, or to repair damage to the body.

Starting with 6.3 g of salicylic acid, how many grams of acetylsalicylic acid (theoretical yield) can be made? Assume salicylic
tensa zangetsu [6.8K]

Answer:

We will produce 8.2 grams of acetylsalicylic acid

Explanation:

step 1: Data given

Mass of salicylic acid, = 6.3 grams

Molar mass salicylic acid = 138.12 g/mol

Molar mass of acetylsalicylic acid = 180.158 g/mol

Step 2: The balanced equation

C7H6O3 + C4H6O3 → C9H8O4 + C2H4O2

Step 3: Calculate moles salicylic acid

Moles salicylic acid = mass salicylic acid / molar mass salicylic acid

Moles salicylic acid = 6.3 grams / 138.12 g/mol

Moles salicylic acid = 0.0456 moles

Step 4: Calculate moles acetylsalicylic acid

Since the mole ratio is 1 to 1

For 0.0456 moles salicylic acid we'll have 0.0456 moles acetylsalicylic acid

Step 5: Calculate mass acetylsalicylic acid

MAss acetylsalicylic acid = moles acetylsalicylic acid * molar mass acetylsalicylic acid

MAss acetylsalicylic acid = 0.0456 moles * 180.158 g/mol

Mass acetylsalicylic acid = 8.2 grams

We will produce 8.2 grams of acetylsalicylic acid

The number of micrograms of contaminant each person will receive is 5,742.64 ug.

<h3>Number of micrograms of contaminant  per person</h3>

The number of micrograms of contaminant each person will receive is calculated as follows;

Amount of contaminant (mg) = (1.01 x 10⁻⁴ mg/mL) x 2.28 x 10⁴ L

Amount of contaminant (mg) = 2.3028 mg.L/mL

Amount of contaminant (mg) = (2.3028 mg.L/mL) x (1000 mL/L) = 2,302.8 mg

Amount of contaminant (ug) = 2,302.8 mg x 1000 ug/mg = 2,302,800 ug

<h3>Amount of contaminant per person (ug/person) </h3>

=  (2,302,800 ug) / (401 persons)

= 5,742.64 ug per person
