Answer:
Volumetric flow rate: Q = 1000 L/s
Explanation:
Volumetric flow rate, also called the rate of fluid flow, is described as volume of fluid that passes a particular point per unit time. The SI unit of volumetric flow rate is m³/s.
Whereas, mass flow rate is defined as the mass of substance that passes through a point per unit of time. SI unit is kg/s.
Given- mass flow rate: ṁ = 1 kg/s and density: ρ = 1 kg/m³
Therefore, volumetric flow rate can be calculated by
Since, 1 m³/s = 1000 L/s
Therefore, volumetric flow rate: Q = 1 m³/s = 1000 L/s
Answer: .
Explanation:
Temperature of the gas is defined as the degree of hotness or coldness of a body. It is expressed in units like and
These units of temperature are inter convertible.
We are given:
Temperature of the gas = (1mK=0.001 K)
Converting this unit of temperature into by using conversion factor:
Thus
Thus the temperature is .

Answer:
6.1 kg
Explanation:
To obtain the total mass of the sample, we must first express each mass of the sample in the same unit of measurement.
Since the SI unit of mass is kilogram (kg), we shall express the total mass of the samples in kilogram (kg).
This is illustrated below:
Mass of the samples are:
M1 = 0.6160959 kg
M2 = 3.225 mg
M3 = 5480.7 g.
Conversion of 3.225 mg to kg
1 mg = 1×10¯⁶ kg
Therefore,
3.225 mg = 3.225 × 1×10¯⁶
3.225 mg = 3.225×10¯⁶ kg
Conversion of 5480.7 g to kg
1000 g = 1 kg
Therefore,
5480.7 g = 5480.7 /1000
5480.7 g = 5.4807 kg
Thus, we can obtain the total mass of the samples as follow:
M1 = 0.6160959 kg
M2 = 3.225×10¯⁶ kg
M3 = 5.4807 kg
Total mass =?
Total mass = M1 + M2 + M3
Total mass = 0.6160959 + 3.225×10¯⁶ + 5.4807
Total mass = 6.096799125 ≈ 6.1 kg
Therefore, the total mass of the samples is approximately 6.1 kg.

Answer:
K.E. = 5.4362 × 10⁻¹⁹ J
Explanation:
The expression for Bohr velocity is:
Applying values for hydrogen atom,
Z = 1
Mass of the electron () is 9.1093×10⁻³¹ kg
Charge of electron (e) is 1.60217662 × 10⁻¹⁹ C
= 8.854×10⁻¹² C² N⁻¹ m⁻²
h is Plank's constant having value = 6.626×10⁻³⁴ m² kg / s
We get that:
Given, n = 2
So,
Kinetic energy is:
So,
K.E. = 5.4362 × 10⁻¹⁹ J
Answer:
- Aluminium sulfate Al2(SO4)3 dissociates in two aluminium ions and three sulfate ions, therefore, van't Hoff factor is 5 (incorrect).
Explanation:
Hello,
In this case, since the van't Hoff factor is related with the species that result from the ionization of a chemical compound, we can see that that
- Aluminium sulfate Al2(SO4)3 dissociates in two aluminium ions and three sulfate ions, therefore, van't Hoff factor is 5 (incorrect).
- Ammonium nitrate NH4NO3 dissociates in one ammonium ions and one nitrate ion, therefore, van't Hoff factor is 2 (correct).
- Sodium sulfate Na2SO4 dissociates in two sodium ions and one sulfate, therefore, van't Hoff factor is 3 (correct).
- Sucrose is not ionized, therefore, van't Hoff factor is 1 (correct).
Best regards.
