Answer:
30.06904
Explanation:
C3H4: Mass % C = 36.033 x 100 / 40.0641 = 89
Molarity is defined by the number of moles of a substance dissolved in a number of liters in solution. 15,000 milliliters is equal to 15 liters, so
2.5/15 = 0.1666... M
The molarity of this solution would be 0.167.
Answer:
20cm=the length of the causation that it loads about the contrasting of the solution it is an easy question to answer it just has too many parts I answered one and I hope it helped to give you a hint towards solving the whole thing good luck

Answer: Set with equal densities are:
15.2 g copper and 50.0 g copper ; 11.2 g gold and 14.9 g gold
Explanation:
Density is defined as mass of the substance present in unit volume of the substance.

It is an intensive property which means that two different masses of same substance will have same value of density under same conditions.
So, from the given samples with equal density are:
- 15.2 g copper and 50.0 g copper will have the same value density.
- 11.2 g gold and 14.9 g gold will have the same value density.
The ice structure takes up more volume than the liquid water molecules, hence ice is less dense than liquid water. What is the exact change in volume of the water when it freezes as ice? Example: Calculate the volume in a 100 g ice cube with a density of 0.92 g per mL.
