Increase
Explanation:
The density of water will increase when sugar is added to it.
Density of all pure samples of a substance are usually the same.
When sugar is added to water, the density will increase.
- Density is defined as the mass per unit volume of a substance.
Density =
Mass is the amount of matter in a substance.
When we add more sugar to water, the solution will have higher mass than that of ordinary water because more substance is now contained in it.

Answer:
112 mL
Explanation:
The formula for percent by volume is
If you have 250 mL of a solution that is 44.8 % v/v,
Answer:
Answer A
Explanation:
2 H2 + O2 = 2 H2O
knowing the mole weights of these elements shows O2 is the limiting reactant in this situation.
4 g oxygen is 4 /31.998 = .125 mole O2
We should get two times these moles of water = .250 moles
weight = .250 (1.008 * 2 + 15.999) = 4.50 gm H20 (theoretical)
....but we only got 4 gm
4/4.50 = 88.8%
