Answer:
v = 10.42 mL
mass = 11.986 g
Explanation:
Given data;
Mass of lotion needed in pound = 0.0264 lb
Density of lotion = 1.15 g/mL
Mass of lotion needed in gram = ?
Volume of lotion needed in mL = ?
Solution:
Mass of lotion needed in gram :
1 pound = 454 g
0.0264 lb × 454 g/ 1lb = 11.986 g
Volume of lotion needed in mL :
d = m/v
1.15 g/mL = 11.986 g / v
v = 11.986 g /1.15 g/mL
v = 10.42 mL
Answer:
Chromatography uses chromatography paper which is filter paper that is made of cellulose, a polymer. Cellulose is polar, therefore it attracts water molecules, as well as other polar substances. As the solvent reacts with the paper, it competes for the attraction of the molecules being separated.

Vinegar is aceti acid diluted in water.
The reaction of vinegar with sodium hydroxide is:
CH3COOH + NaOH ---> CH3COONa + H2O
That is an acid-base reaction.
The speed of reaction is proportional to the concentrations of the reactants.
Then, given thatn when you dilute the vinegar you decrease the concentration of CH3COOH, the rate of reaction will decrease.
Answer: decrease the rate of reaction.
If the partial pressure of CO₂ in a bottle of carbonated water decreases from 4.60 atm to 1.28 atm, the mass of CO₂ released is 0.265 g.
The partial pressure of CO₂ gas in a bottle of carbonated water is 4.60 atm at 25 ºC. We can calculate the concentration of CO₂ using Henry's law.

We can calculate the mass of CO₂ in 1.1 L considering its molar mass is 44.01 g/mol.

Now, we will repeat the same procedure for a partial pressure of 1.28 atm.


The mass of CO₂ released will be equal to the difference in the masses at the different pressures.

If the partial pressure of CO₂ in a bottle of carbonated water decreases from 4.60 atm to 1.28 atm, the mass of CO₂ released is 0.265 g.

<em>The partial pressure of CO₂ gas in a bottle of carbonated water is 4.60 atm at 25 ºC. How much CO₂ gas (in g) will be released from 1.1 L of the carbonated water when the partial pressure of CO2 is lowered to 1.28 atm? At 25 ºC, the Henry’s law constant for CO₂ dissolved in water is 1.65 x 10⁻³ M/atm, and the density of water is 1.0 g/cm³.</em>
