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
A + B = Products
This is the correct mechanism.
Answer:
Einstein tells us that the relationship between energy and matter is defined by the equation E
=
M
C
2
, where E is energy, and M is mass.
Explanation:
By looking at Einstein's equation we can see that matter (or something that has mass) and energy are actually the same thing
Answer:
The pH scale is used to express the concentrations of hydronium ions and potassium ions in solutions.
Explanation:
The mass of a magnesium block that measures 2.5cm x 3.5cm x 1.5cm, the correct answer would be option “B.”
