Answer:
Density is 7.15 g /mL.
Mass is 445.2 g.
Explanation:
Density:
Density is equal to the mass of substance divided by its volume.
Units:
SI unit of density is Kg/m3.
Other units are given below,
g/cm3, g/mL , kg/L
Formula:
D=m/v
D= density
m=mass
V=volume
Symbol:
The symbol used for density is called rho. It is represented by ρ. However letter D can also be used to represent the density.
Given data:
Mass of first zinc sample = 210.10 g
Mass of second zinc sample = 235.10 g
Combined volume = 62.3 mL
Density of combined sample ?
Mass of combined sample = ?
Solution:
Mass of combined sample = 210.10 g + 235.10 g = 445.2 g
density = mass / volume
density = 445.2 g / 62.3 mL
density = 7.15 g /mL

Answer:
1.1 × 10⁻⁴ M
Explanation:
Let's consider the following double displacement reaction.
CuCl₂(aq) + 2 AgNO₃(aq) → 2 AgCl(s)+ Cu(NO₃)₂(aq)
We can establish the following relations:
- The molar mass of AgCl is 143.32 g/mol.
- The molar ratio of AgCl to CuCl₂ is 2:1
The moles of CuCl₂ that reacted to produce 7.7 mg of AgCl are:
The molarity of CuCl₂ is:
