Answer:
High tides and low tides are caused by the moon. The moon's gravitational pull generates something called the tidal force. The tidal force causes Earth—and its water—to bulge out on the side closest to the moon and the side farthest from the moon. ... When you're not in one of the bulges, you experience a low tide.
The number of moles of the gas at 77°C and 1.33 atm occupies a volume of 50.3 L is 2.35 moles. It can found with the help of Ideal gas equation.
<h3>What is Ideal Gas equation ? </h3>
The ideal gas equation is formulated as : PV = nRT.
In this equation, P refers to the pressure of the ideal gas, V is the volume of the ideal gas, n is the total amount of ideal gas that is measured in terms of moles, R is the universal gas constant, and T is the temperature.
Given ;
- Pressure = 1.33 atm
- Volume = 50.3 ltr
- Temperature = 77 (+273 k) = 350K
We know ;
- Gas constant (R) = 0.081 L atm/mol K
Formula used ;
n = PV / RT
n = 1.33 x 50.3 / 0.081 x 350k
= 2.35 moles.
Hence, The number of moles of the gas at 77°C and 1.33 atm occupies a volume of 50.3 L is 2.35 moles

Answer:
mi = 31.28 g
Explanation:
According to the law of conservation of energy:
where,
mi = mass of ice = ?
L = Latent heat of fusion of ice = 334 J/g
mw = mass of water = 50 g
C = specific heat of water = 4.18 J/g.°C
ΔT = change in temperature of water = 75°C - 25°C = 50°C
Therefore,
<u>mi = 31.28 g</u>
