What is the mass in grams of 300 ml of salt water with a density of 1.30 g/cm^3

The mass of salt water is 390 grams

Explanation:

To calculate the mass of salt water, we use the equation:

Density of salt water =

Volume of salt water = 300 mL =   (Conversion factor: )

Putting values in above equation, we get:

Hence, the mass of salt water is 390 grams

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.
