The density of the unknown liquid has a mass of 7.553g is 0.7553 g/ml
<h3>What is density?</h3>
Density is the measurement of how tightly a material is packed together.
Given data:
Weight =7.553g
Volume = 10.0ml
Density =
Density =
Density = 0.7553 g/ml
Hence, the density of the unknown liquid has a mass of 7.553g is 0.7553 g/ml.

First write out the balanced equation. 3Cu+2Ag(NO3)3=2Ag+3Cu(NO3)2
Then convert copper from grams to moles
15 g*1 mol cu/63.54 g= 15/63.54 mol cu
Then use the mole ratio to convert Moles Cu to Moles Ag
15/63.54 moles Cu* 2 moles Ag/3 moles Cu
The final awnser is (15*2)/(63.54*3) moles Ag =0.157 moles Ag. If the question wants the answer in grams, convert from moles Ag to grams Ag.
0.157 moles Ag*107.87 g Ag/ mol Ag=16.98 g Ag
Explanation:
High density medium to low density medium.
Formula: % by mass = (mass of solute / mass of solution] *100
Data:
mass of solution = 80.85 g
% by mass = 22.4%
Unknown = mass of solute
Solution
% by mass = (mass of solute / mass of solution] *100 = >
mass of solute = % by mass * mass of solution / 100
mass of solute = 22.4 * 80.85 / 100 = 18.11 g
Answer: 18.11 g
Freezing Point of Sea water would be lower than that of Pure Water. It is because of salinity of the water
