Answer:
0.64 M
Explanation:
Step 1: Given data
- Initial concentration (C₁): 1.0 M
- Initial volume (V₁): 16 mL
- Final concentration (C₂): ?
Step 2: Calculate the final concentration of the dextrose solution
We want to prepare a diluted solution from a concentrated one. We can find the final concentration using the dilution rule.
C₁ × V₁ = C₂ × V₂
C₂ = C₁ × V₁ / V₂
C₂ = 1.0 M × 16 mL / 25 mL
C₂ = 0.64 M
Answer:
Gamma Rays
Gamma Rays-have the smallest wavelengths and the most energy of any other wave in the electromagnetic spectrum.
Explanation:
Explanation:
To remove the salt from the oil, I will add water to dissolve the salt from it.
Oil is an organic molecule that is non-polar
Salt is polar ionic compound
Salt will not dissolve in the oil.
- Take the mixture.
- Add water to it.
- Water and oil are immiscible
- Shake the new heterogeneous mixture vigorously.
- leave to settle.
- Oil will come on top of the water.
- You can skim off the oil layer on top.
- Then heat the water and salt solution.
- This leaves the oil behind.

Answer: -
24 grams per kilogram.
Explanation: -
We know that
The mixing ratio = actual (measured) mass of water vapor (in parcel) in grams / mass of dry (non water vapor) air (in parcel) in kilogram
The saturation mixing ratio = mass of water vapor required for saturation (in parcel) in grams/ mass of dry (non water vapor) air (in parcel) in kilograms
Relative humidity = actual (measured) water vapor content/ maximum possible water vapor amount (saturation)
Thus saturation mixing ratio = Mixing ratio / relative humidity
= 6 / (25/100)
= 24
