1.27g
Explanation:
Given parameters:
Number of moles of C₂₀H₄₂ = 4.52 x 10⁻³moles
Unknown:
Mass of the compound = ?
Solution:
The mole is a comfortable unit for measuring chemical substances.
number of moles =
Molar mass of C₂₀H₄₂ = (12 x 20) + (1 x 42) = 240 + 42 = 282g/mol
Mass of the compound = number of moles x molar mass
= 4.52 x 10⁻³ x 282
= 1.27g

Answer:
4.09ₓ10²³ atoms are contained in 10g of C₃H₈
Explanation:
1 mol of C₃H₈ has 3 mol of carbon and 8 mol of hydrogen.
1 mol of C₃H₈ weighs 44 g
In 44 g of C₃H₈ we have 3 mol of C
In 10 g of C₃H₈ we'll have (10 . 3)/ 44 = 0.681 mol
1 mol of C has NA (6.02x10²³) particles
0.681 mol will have (0.681 . 6.02x10²³) = 4.09ₓ10²³ atoms

Okay ask away. . . You haven't asked anything that we would be able to answer
<h2>Plasma is most likely inflence by - Option C</h2>
This plasma is most likely influenced by magnetic and electric fields. The massive positively charged ions which are influenced the lighter electrons than replace the ions to keep charge impartiality.
Therefore electric field influence the plasma. The movement of charged particles identical to a magnetic field line is not influenced. Plasma contains charged particles which are positive nuclei and negative electrons which can be molded and restricted by magnetic forces.
Alike iron filings in the closeness of a magnet, bits in the plasma will ensue magnetic field lines.
Answer:
<h2>The answer is 6 J</h2>
Explanation:
The kinetic energy of an object can be found by using the formula
where
m is the mass
v is the velocity
From the question we have
We have the final answer as
<h3>6 J</h3>
