Answer:
The jewelry is 2896.54_Kg/m^3 less dense than pure silver
Explanation:
Density of jewellery = (mass of jewellery) ÷ (volume of jewellery)
=3.25g ÷ 0.428mL = 0.00325Kg÷0.000000428m^3 = 7583.46Kg/m^3
The density of silver is 10490_Kg/m^3 which is (10490 - 7583.46) 2896.54_Kg/m^3 more dense than the jewellery
The density of Silver [Ag]
The weight of Silver per cubic centimeter is 10.49 grams or the weight of silver per cubic meter is 10490 kilograms, that is the density of silver is 10490 kg/m³; at 20°C (68°F or 293.15K) at a pressure of one atmospheres.
Answer:
Concentration of dissolved salts = 34,038.76 ppm
Explanation:
Given:
Salinity of ocean water = 34
Find:
Concentration of dissolved salts
Computation:
Salinity of ocean water = 34 g/l
1g/l = 1001.14 ppm
Concentration of dissolved salts = 1001.14 ppm x 34
Concentration of dissolved salts = 34,038.76 ppm
