<span>16 = m x 1.86
m = 8.60 = moles solute / 6.50 Kg
moles solute = 55.9
mass solute = 55.9 x 62.068 g/mol=3470 g
V = 3479/ 1.11 =3126 mL= 3.13 L
delta T = 8.60 x 0.512 =4.40
boling point = 104.4 °C
Hope this helps.</span>
Minerals, Because when wind blows everything and crushes rocks into minerals.
Please make me brainy answer
The density of the sample is:
Density = mass / volume
Density = 9.85 / 0.675
Density = 14.6 g/cm³
If the sample has 95% gold, and 5% silver, its density should be:
0.95 x 19.3 + 0.05 x 10.5
Theoretical density = 18.9 g/cm³
The difference in theoretical and actual densities is very large, making it likely that the jeweler was not telling the truth.
