Answer:
Fluorine
Explanation:
Data obtained from the question include:
The isotope of fluorine has:
Proton = 9
Neutron = 10
The atomic number is the proton number of the atom.
Therefore, the atomic number = 9
Mass number = proton + Neutron
Mass number = 9 + 10
Mass number = 19
Now comparing the above with the fluorine atom in the periodic table. We'll discover that the isotope is actually fluorine atom.
Therefore, the name of the isotope is fluorine
Answer:
0.3811 mol.
Explanation:
- To calculate the no. of moles of a gas, we can use the general law of ideal gas: <em>PV = nRT</em>.
where, P is the pressure of the gas in atm.
V is the volume of the gas in L.
n is the no. of moles of the gas in mol.
R is the general gas constant,
T is the temperature of the gas in K.
∵ P = 2.1 atm, V = 4.5 L, T = 302 K, R = 0.0821 L.atm/mol.K.
<em>∴ n = PV/RT </em>= (2.1 atm)(4.5 L)/(0.0821 L.atm/mol.K)(302.0 K) = <em>0.3811 mol.</em>

Answer: All solutions have two parts: the solute and the solvent. The solute is the substance that dissolves, and the solvent is the substance that dissolves the solute.
Hope that helps (:
