<h3><u>Answer</u>;</h3>
pH = 3.03
<h3><u>Explanation</u>;</h3>
NaCl is a neutral salt and does not affect the pH.
moles HCl = g HCl / MM
= 16.5 / 36.5
= 0.452 equivalent to moles H+
Molarity H+ = moles H+ / L
= 0.452 / 482
= 0.000938 M
Hence; pH = -log[H+]
= -log(0.000938)
= 3.03
Answer:
Molecular weight of the compound = 372.13 g/mol
Explanation:
Depression in freezing point is related with molality of the solution as:
Where,
= Depression in freezing point
= Molal depression constant
m = Molality
m = 0.26
Molality =
Mass of solvent (toluene) = 15.0 g = 0.015 kg
Moles of compound = 0.015 × 0.26 = 0.00389 mol
Mass of the compound = 1.450 g
Molecular weight =
Answer:
Both fission and fusion are nuclear reactions that produce energy, but the applications are not the same. Fission is the splitting of a heavy, unstable nucleus into two lighter nuclei, and fusion is the process where two light nuclei combine together releasing vast amounts of energy.

Answer:
ratio=0.996m/s
Explanation:
; M= molecular weight of compound;
RMS speed is inversly proportional to the molecular weight hence compound having less molecular weight will have more rms speed value.
