yaroslaw [1]
The solar system is made up of the sun and everything that orbits around it, including planets, moons, asteroids, comets and meteoroids. It extends from the sun, called Sol by the ancient Romans, and goes past the four inner planets, through the Asteroid Belt to the four gas giants and on to the disk-shaped Kuiper Belt and far beyond to the teardrop-shaped heliopause. Scientists estimate that the edge of the solar system is about 9 billion miles (15 billion kilometers) from the sun. Beyond the heliopause lies the giant, spherical Oort Cloud, which is thought to surround the solar system.

HELP PLEASE 40.0 grams of salt are dissolved in 100. grams of water. The solution is how many grams?
garik1379 [7]

Answer:

The mass of the solution is 140 grams.

Explanation:

The mass of the solution is given by the sum of the solute's mass and the solvent's mass:

m_{sol} = m_{ste} + m_{svt}

Where:

m_{sol}: is the mass of the solution

m_{ste}: is the mass of the solute

m_{svt}: is the mass of the solvent

The solute is the salt (40.0 g) and the solvent is the water (100 g), so:

m_{sol} = m_{ste} + m_{svt} = 40 g + 100 g = 140 g

Therefore, the mass of the solution is 140 grams.

I hope it helps you!
