Answer:
Likely (indium.)
Explanation:
Number of atoms: .
Dividing, , the number of atoms by the Avogadro constant, , would give the number of moles of atoms in this sample:
.
The mass of that many atom is . Estimate the average mass of one mole of atoms in this sample:
.
The average mass of one mole of atoms of an element ( in this example) is numerically equal to the average atomic mass of that element. Refer to a modern periodic table and look for the element with average atomic mass . Indium, , is the closest match.
Short Answer: <span>Solutions of dilute, weak acids - the only kind that you might taste - are sour. Weak, dilute bases are bitter. Solutions of bases are slippery.

A positively charged nucleus with two protons and two neutrons hope this helps :)
Use the formula:
P1V1/T1N1 = P2V2/T2N2
You can cross out T1,N1,T2, and N2 because you are working with pressure and volume in this equation.
Now, you are left with Boyle’s Law:
P1V1 = P2V2
Substitute the values in
STP = 1 atm for pressure
(1 atm)(2.1L) = P2 (0.125 L) [I converted 125 ml to liters so they would be the same unit]
Now, divide both sides by 0.125 to find P2
P2 = (1 atm)(2.1 L)/(0.125 L)
Liters cancel out
P2 = 16.8 atm
