Answer:
it depends where you live really... lol
Answer:
The answer to your question is 9.034 x 10²³ molecules
Explanation:
Data
number of molecules = ?
number of moles = 1.50
Process
To solve this problem, use Avogadro's number. This number relates 1 mol of a substance to 6.023 x 10²³ molecules.
1 mol of CO₂ --------------- 6.023 x 10 ²³ molecules
1.5 moles of CO₂ ---------- x
x = (1.5 x 6.023 x 10²³) / 1
x = 9.034 x 10²³ molecules
Circumpolar constellations stay in the sky. Because of the rotation of the Earth and its orbit around the Sun, we divide the stars and constellations into two groups. Some stars & constellations never rise nor set, and they are called circumpolar.
The formula for hyposulfurous acid is H2SO2.
Answer:
1.02
Explanation:
By the third Kepler's Law for an elliptic orbital, such as the Earth and the Sun:
T² = R³/k
Where T is the period of the rotation (in years), R is the distance between the planet to the star (in au), and k is the constant which depends on the mass of the star. For Earth and Sun, T = 1 year, and R = 1 au, so k = 1.
For HD 10180g, T = 600/365 = 1.64 years, R = 1.4
(1.64)² = (1.4)³/k
k = 2.744/2.6896
k = 1.02
Because k only depends on the mass, we can conclude that the ratio of the star's mass to our sun's mass is the ratio of the k values, so it will be:
1.02/1
1.02
