Answer:
0° Celsius
Explanation:
The thermometer shows 0° Celsius which corresponds to 32° F.
The correct answer is B. The concentration of a solution does not decreases when you add more solute to the solvent. Instead, the concentration increases. Concentration is expressed as the amount of solute per unit of solvent. Therefore, increasing the solute, increases this value and increasing the solvent, decreases this value.
Answer:
0.313L
Explanation:
0.25Mx1.00L=0.80Mx V2
so, 0.25x1.00/0.80=0.313L
Erica is likely to use reverse osmosis process.it is the method used in the industry to treat water in oil and gas industry .or ultra filtration method is also employed
The answer is- Volume of flask = 247.8
or 247.8 mL.
Density (d) is defined as mass of substance divided by its volume. Thus, if mass and density are known, then Volume can be determined.
What is the formula of volume in terms of density?
- Let mass of substance be 'm' and volume be 'V'. Thus, as per the definition of density, it is expressed as-

Thus, volume can be expressed as-

- Now, mass of empty flask = 241.3 g and the mass of (flask + Water) = 489.1 g.
Thus, mass of water =
.
- Thus, mass of water = 247.8 g and density of water =
. Its volume is calculated as-

- Hence, volume of flask = 247.8
or 247.8 mL.
