Answer:
~1.5 g/cm3 and it does NOT float in water.
Explanation:
If you look at the graph, Object A weighs ~6 grams and is ~4 cm3 in volume
Density = Mass/Volume
So 6 grams/4 cm3 = 1.5 g/cm3
Water has a density of 1 g/cm3 and because Object A density is higher than that of water, it sinks.

Answer:
= 152.40 g
Explanation:
The equation for the reaction is;
Cu(s) + AgNO3 → Ag(s) + Cu(NO3)2
Mass of silver nitrate = 320.0 g × 0.75
= 240.0 g
Molar mass of silver nitrate = 169.87 g/mol
Therefore;
Moles of silver nitrate = 240.0 g/169.87 g/mol
= 1.413 moles
Mole ratio of Silver nitrate to silver metal = 1 : 1
Therefore, moles of silver metal = 1.413 moles
Hence;
Mass of silver metal = 1.413 moles × 107.868 g/mol
<u>= 152.40 g</u>
