4. The woman's auxiliary at the Fire Company need to make 250 one pound pie crusts for a fund raiser. If each pie crust has a mass percent of 35% flour, how many 10 pound bags of flour should they buy?
(5 points)
Mass % = (mass of component) x 100
(total mass of mixture )

i rly did this for the extra points sry btw its d tho

Explanation:

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.
