Jonathan wants to find the density of a lead fishing weight. He measures the weight's mass at 342.0 grams. He then puts the lead weight into a graduated cylinder filled with 200 milliliters of water. He sees that the water level rises to 240.0 milliliters. What is the density of the lead weight? A) 440mL

B) 542g/mL

C) 0.78g/mL

D) 8.55g/mL

figure it out

Explanation:

n has four pairs of electrons in the valence shell, electrons repel one another ,n has 7 protons in its nucleus, and since n has 7 protons, it must fill the second shell, giving it 4 pairs of electrons. the electrons form 3 bonds and 1 lone pair of electrons. each pair of electrons repels the other pairs, so they are equally far apart.

so all of the above

43.452

step-by-step explanation:

284 times .153 = 43.452
