Answer:
The answer to your question is: c) ATP
Explanation:
a) Carbon dioxide this molecule is a product of cell respiration so is very important for the cells but it isn't a form of energy cash, then this option is wrong.
b)Glucose: this molecule is used in the cell respiration process, from it the cell obtain ATP, but it isn't the energy cash for the cell.
c) ATP: this molecule is used by the cell to obtain energy, when an enzyme cuts off the phosphate bonds of this molecule it gets energy so this is the right answer.
d) Oxygen: oxygen is very important in the cell respiration process but It isn't usedas a energy cash.
I'm pretty sure it's A, but then again I'm only in 8th grade. Sorry if this doesn't help:(
Henry law:
P = KC
P = solvent vapour pressure
K = Henry constant
C = conc of solute
So, 0.2 = 773 C
so, C = 0.2 / 773 = 2.5 x 10^{-4} molal
The answer is- Mass of flask = 608.04 g
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 mass 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, mass 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-
- Volume of flask = 247.8
. - Then when this flask is filled with chloroform (d =
), the mass of chloroform is-
- Hence, the mass of flask becomes =
