Answer:
1.8g
Explanation:
Initial volume = 43.5ml
Final volume = 49.4ml
Mass = 10.88g
Density = ?
Volume = Final volume - initial volume
= 49.4 - 43.5
= 5.9ml
Density = Mass/volume
Density = 10.88/5.9
= 1.8g/ml

Explanation:
2 and 3, because there are the protons and neutrons which have a greater mass than the electrons which are found in the locations 1 and 4.
Explanation:
The atom contains a nucleus, which is made from protons and neutrons, and electrons which are found around the nucleus.
The mass of the atoms is concentrated in the very tiny space represented by the nucleus. Of course the electrons have a mass too, but is very small compared to the protons and neutrons, and we usually neglect its mass.

Answer:
3.4 moles of silver * 107.868 grams of silver/1 mole of silver = 370 grams of silver.
Explanation:
According to the NYS Reference Table, one mole of silver equates to 107.868 grams. Therefore, if you want to convert from moles to grams, the mole unit should be on the bottom, since it is the unit being cancelled out. Above the mole unit should be the gram unit, since it is the unit you want to convert to. Once you do the math with significant figures, the solution turns out to be 370 grams of silver.
