Answer:
0.278 mol HCl
Explanation:
We currently have 185.0 mL of a 1.50 mol/L solution of HCl. We want to find the number of moles there are.
Based on the given information, our volume is 185.0 mL and our molarity is 1.50. Because molarity is defined as moles / Litre, we can easily find the moles given volume by multiplying molarity by volume.
First, though, we must convert millilitres to litres. There are 1000 mL in 1 L, so divide 185.0 by 1000:
185.0 / 1000 = 0.185 L
Now, multiply 0.185 by 1.50:
0.185 L * 1.50 mol/L = 0.278 mol HCl
Thus the answer is 0.278 mol HCl.

According to boiling point elevation equation:
Δ T = i Kb m
when ΔT (change in boiling point) = 7.10 C°
and i (van't Hoff factor)= 1
and Kb = 0.520
so, by substitution:
7.10 = 1*0.520 *m
m = 7.1 / 0.52 = 13.65 m
Thermal energy equation is;
Q = mcΔθ
Q = Thermal energy
m = mass
c = specific heat
Δθ = Temperature difference
the hot cup of coffee has a higher temperature. But the mass of coffee is very low compared to the mass of water in swimming pool. The maximum temperature for coffee only can go up to 100 ⁰C since the boiling point of water is 100 ⁰C. But the mass of water in swimming pool is very large and the thermal enegy is very high compared to the coffee cup due to that reason.
