Solution here,
Volume(V)=67.4 L
Pressure(P)=1 atm
Temperature(T)=(0+273)K=273K
Universal gas constant(R)=0.0821 L.atm.mol^-1K^-1
No. of moles(n)=?
Now,
PV=nRT
or, 1×67.4=n×0.0821×273
or, 67.4=22.4n
or, n=67.4/22.4
or, n=3
therefore, required no. of mole is 3.
Answer:
4 is the answer
Explanation:
i am not sure for this question
BaSO4 is the correct formula for barium (ll) sulfate
The answer is D. A positively charged sodium Ion and a negatively charged chlorine ion form an ionic bond.
The concentration of the hydrogen ions from molarity can be given with the number of hydrogen atoms in the molecular formula.
<h3>What is molarity?</h3>
Molarity is given as the moles of the solute present in a liters of solution. The compound with the number of hydrogen atoms in the molecular formula with degradation possesses the equivalent concentration of the hydrogen ions.
The compound with molecular formula AH having molarity 2, will produce 2M of hydrogen ions.
