I cant see anything, can you provide a picture or something please
Answer:
Mars has an orbit with a semimajor axis of 1.524 astronomical units (228 million km), and an eccentricity of 0.0934 The planet orbits the Sun in 687 days and travels 9.55 AU in doing so making the average orbital speed 24 km/s.
The eccentricity is greater than that of every other planet except Mercury, and this causes a large difference between the aphelion and perihelion distances—they are 1.6660 and 1.3814 AU
Explanation:
The -1 charge means that there is one more electron than protons, so there are 85 protons
20.91200832 g of must be dissolved in 0.504 L of a solution to make a 0.56 M solution.
What is the molarity of a solution?
Molarity (M) is the amount of a substance in a certain volume of solution. Molarity is defined as the moles of a solute per litres of a solution. Molarity is also known as the molar concentration of a solution.
Given data:
The volume of solution= 0.504 L
Molarity of = 0.56 M
Step 1: Calculating the mass of
Putting the given values in the equation.
Moles of solute = 0.28224
Molar mass of = 74.093 g/mol
Now, put the values in the formula.
Mass of =20.91200832 g
Hence, 20.91200832 g of must be dissolved in 0.504 L of a solution to make a 0.56 M solution.
