101.55 M mL= 22.5 M mL + 1.50x M
101.55 M mL - 22.5 M mL = 1.50x M
79.05 M mL = 1.50 M
79.05 M mL / 1.50 M = x

59.7 mL needs to be added to the original 15.00 mL solution in order to dilute it from 6.77 M to 1.50 M.

When 10 grams of water completely evaporate into water vapor, the volume of the water vapor is greater than the volume of the original liquid water, but the mass remains the same. Why does the mass stay the same? Which answer is correct?
A
The temperature of the liquid water and water vapor is the same.
The temperature of the liquid water and water vapor is the same.
B
The density of the liquid water is the same as the density of the water vapor.
The density of the liquid water is the same as the density of the water vapor.
C
The number of atoms in the water vapor is equal to the number of atoms in the liquid water.
The number of atoms in the water vapor is equal to the number of atoms in the liquid water.
D
The distance between the water molecules is the same in the liquid and the vapor.
The distance between the water molecules is the same in the liquid and the vapor.
Answers
Answer: I think the answer is B or C, its kind of hard.
As the number of atoms in the water vapor is equal to the number of atoms in the liquid water. Therefore, the mass of the water remains the same.
What is evaporation?Evaporation is a process that usually happens on the surface of water or liquid and it involves the conversion of the liquid phase into the gaseous phase. This process involves a change in the state of matter of water or liquids.
When the water is completely evaporated into water vapor the density of the water vapor is less than the density of the liquid water as the vapors occupy a large volume in comparison to liquid water.
But the number of atoms in the water vapor is the same as the number of atoms in the liquid water. The mass of the water is due to the mass of the atoms.
Therefore, the mass of the water remains the same during the phase transition from liquid water to water vapors. Therefore, option (C) is correct.

Sodium chloride
Explanation:
There are several salts in seawater, but the most abundant is ordinary table salt or sodium chloride (NaCl). Sodium chloride, like other salts, dissolves in water into its ions, so this is really a question about which ions are present in the greatest concentration.

1. If you have 5g of pennies how many dozen pennies do you have?
Answers
Answer:
15.69 dozen
Explanation:
Mass of penny = 5 g
Dozens of penny =..?
Next, we shall convert 5 g to gross. This can be obtained as follow:
3824 g = 1000 gross
Therefore,
5 g = 5 g × 1000 gross / 3824 g
5 g = 1.3075 gross
Thus, 5 g is equivalent to 1.3075 gross.
Finally, we convert 1.3075 gross to dozen. This can be obtained as follow:
1 gross = 12 dozen
Therefore,
1.3075 gross = 1.3075 gross × 12 dozen / 1 gross
1.3075 gross = 15.69 dozen
Thus, 5 g of penny is equivalent to 15.69 dozen

Answers
Answer:
373 K; 253 K
0°C ; -258°C
Explanation:
In order to change Temperatures to Absolute Value (Kelvin) you shoud do this sum:
T° in C + 273 = T° in K
For question 1:
100°C + 273 = 373K
-20°C + 273 = 253K
For question 2:
T° K - 273 = T° C
273 K - 273 = 0°C
15 k + 273 = -258 °C
