The volume of a sample is its unique property, which can be defined as the mass of the material per unit volume of that material. Now as per Archimedes law if a material is submerge in a liquid the increased volume of the liquid will be equivalent to the volume of the material.
Here due to addition of the Jade the volume of the liquid increases from 50 to 60.5 mL. Thus the change of the volume is (60.5-50) = 10.5 mL, which will be equivalent to the volume of the Jade. Thus the volume of the Jade is 10.5 mL and its density 3.3 g/cm³. Now as 1 mL = 1 cm³ thus the density can be rewritten as 3.3 g/mL. So 1 mL of the Jade has the mass 3.3 g, thus 10.5 mL of the Jade will have (10.5×3.3) = 34.65 g of mass.
The mass of the piece of Jade is 34.65 g.
Answer : The empirical formula is 
.
Explanation :
Molecular formula : It is represented by the actual number of the atoms of all the elements present in a compound.
Empirical formula : It is represented by the simplest whole number of the atoms of all the elements present in a compound.
The given molecular formula is .
For determining the empirical formula, we need to determine the valency which is divided by each element to get the empirical formula.
In the given formula, the valence is 1.
So, the empirical formula is .
Answer:Cl2(aq) + 2Br–(aq) Right arrow. 2Cl–(aq) + Br2(aq) Bromine (Br) is the oxidizing agent because it gains an electron. Bromine (Br) is the oxidizing agent because it loses an ele
