You go fishing and obtain some less weights for your trip. Lead’s density is 11.34 g/mL. If there are 50 weights in a 250 mL box, what is the mass of each weight?

Mass of each weight = 56.7 gram per piece

Explanation:

Given:

Lead’s density = 11.34 g/mL

Number of weights = 50

Volume of box = 250 mL

Find:

Mass of each weight

Computation:

Mass = volume x density

Mass = 250 x 11.34

Mass = 2,835 gram

Mass of each weight = Total Mass / Number of weights

Mass of each weight = 2,835 / 50

Mass of each weight = 56.7 gram per piece

"among the transition metal elements, manganese and zinc have a slight lowering of electronegativities. the reason behind this is that the nuclear charges of these elements are slightly weaker than the other transition metal elements due to the way their valence electrons are filled up. both manganese and zinc have their valence electrons filled up to the 4th shell with 1 pair of electrons (4s2) completely occupying it. although the electrons in the 3rd shell (3d) are yet to be paired since the outer most shell is filled up, the ability of the nucleus to attract electrons is lessened. hence,   the electronegativity (or the ability to attract electrons) is lessened."

indicate valleys, hills, steepness and gentleness of slopes.

explanation:

contour lines on a map indicate elevation, or depth. numeric notations on contour lines refer to the level of elevation, or height about sea level.
