A recipe for spaghetti souce requires 2.5 cups of tomato sauce. If only metric measures are available, how many milliliters of tomato sauce are needed?(1qt = 4 cups, 1q = 946 mL)

591.25ml

Explanation:

4 cups=946ml

0.5cups=946÷8=118.25ml

2.5cups=118.25ml*5=591.25ml

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.
