Answer:
The dose of Elixophyllin for a person of 160 lb is 436.36 mg.
Explanation:
First you have to go from pounds to kilograms. 160 lb x 1kg/2.2lb = 72.73 kg.
Then you have to multiply the dosage by the body mass in kilograms.
(6 mg/kg) x 72.73 kg ⇒ 436.36 mg.
13 bars
B.
27 bars
C.
41 bars
That would be 13 bars
A. 13 bars
the correct answer is A. because 1 gold bar's volume is 36cm so what you do is divide 500cm into 36cm and the answer is 13.8888889 bars would have the volume of 500cm so the approximate answer is 13 bars
No, because a child under the age of 16 does not have the right to engage in such relationships and it's punishable by law if the relationship becomes intimate.
no that is inappropriate he could go to jail!
Given:
Volume of Na2CO3 = 250 ml = 0.250 L
Molarity of Na2CO3 = 6.0 M
Volume of CaF2 = 750 ml = 0.750 L
Molarity of CaF2 = 1.0 M
To determine:
The mass of CaCO3 produced
Explanation:
Na2CO3 + CaF2 → CaCO3 + 2NaF
Based on the reaction stoichiometry:
1 mole of Na2CO3 reacts with 1 moles of Caf2 to produce 1 mole of caco3
Moles of Na2CO3 present = V * M = 0.250 L * 6.0 moles/L = 1.5 moles
Moles of CaF2 present = V* M = 0.750 * 1 = 0.750 moles
CaF2 is the limiting reagent
Thus, # moles of CaCO3 produced = 0.750 moles
Molar mass of CaCO3 = 100 g/mol
Mass of CaCO3 produced = 0.750 moles * 100 g/mol = 75 g
Ans: Mass of CaCO3 produced = 75 g
