Answer: Pigment.
Explanation: Our hair color is determined by two types of pigment, Eumelanins, and Pheomelanins. Which together produces all the natural hair colors we see every day with other people.
The arctic climate most likely
Answer:
0.9359 M
Explanation:
M(CaCO3)=100.1 g/mol
10.305 g * 1 mol/100.1 g = 10.305/100.1 mol CaCO3
(10.305/100.1 mol )/0.1100 L = 0.936 mol/L = 0.9359 M
Answer:
7.68 × 10²⁴
Explanation:
Step 1: Calculate the mass of 1 molecule of the monomer CH₂CHCN
We will get the mass of the monomer by adding the masses of the elements.
mCH₂CHCN = 3 × mC + 3 × mH + 1 × mN
mCH₂CHCN = 3 × 12.01 amu + 3 × 1.01 amu + 1 × 14.01 amu = 53.07 amu
Step 2: Convert the mass of the monomer to grams
We will use the conversion factor 1 amu = 1.66 × 10⁻²⁴ g
53.07 amu × 1.66 × 10⁻²⁴ g/1 amu = 8.81 × 10⁻²³ g
Step 3: Calculate "n"
We will divide the mass of the polymer by the mass of the monomer.
n = 676.8 g / 8.81 × 10⁻²³ g = 7.68 × 10²⁴
