Answer:
One serving is 1/4 cup therefore 1 cup would be 4 servings. Since we have 9 cups we would then multiply 9 x 4 and the answer would be 36 servings. You have a ratio of cups to serving, so 1/4 cup : 1 serving, or .
Explanation:
Answer:
the answer is B.
No, as ionic compounds are only conductive in an aqueous (water) solution
Explanation: i just know
Answer: There are 
molecules present in 7.62 L of 
at 
and 722 torr.
Explanation:
Given : Volume = 7.62 L
Temperature = 
Pressure = 722 torr
1 torr = 0.00131579
Converting torr into atm as follows.
Therefore, using the ideal gas equation the number of moles are calculated as follows.
PV = nRT
where,
P = pressure
V = volume
n = number of moles
R = gas constant = 0.0821 L atm/mol K
T = temperature
Substitute the values into above formula as follows.
According to the mole concept, 1 mole of every substance contains 
atoms. Hence, number of atoms or molecules present in 0.244 mol are calculated as follows.
Thus, we can conclude that there are molecules present in 7.62 L of at and 722 torr.
The mass percent of each compound is
- (NaBr*2H2O)=85.71 percent
- (MgBr2*6H2O)=14.29 percent
<h3>The mass percent equation is as follows.</h3>
The formula mass percent is the most effective way to express mass percent: mass percent = (mass of chemical x total mass of compound) times 100. Add 100 to the top value to get the value expressed as a percentage.
<h3>What percentage by mass does a solution have?</h3>
By multiply the grams of solute per gram of solution by 100, it is possible to get the mass percent of a solution.
The molar mass of each element and the mass of each element contained in a mole of the compound are both solved for in the Mass Percent formula.
