Because the gmm for chlorine is 35.5 which is the average of all of those combined, so the percentages reflect how much of each isotope is needed to make the average that specific mass per mole
Answer: option B. there are 35 mg of lead in 1.0 L of this solution
Explanation:
1ppm = 1mg/L
Therefore 35ppm = 35mg/L
So, the solution contains 35mg of lead in 1L of the solution
radiation is energy that comes from a source. (travels through the speed of light)
Answer:
The volume is the same for any gas.
Explanation:
<em>Which describes the volume of 1 mol of gas at standard temperature and pressure?
</em>
- <em>The volume is greater for a larger mass of gas.</em> FALSE. The volume depends on the amount of matter (moles) and not on the mass.
- <em>The volume is the same for any gas.
</em> TRUE. The volume of any gas at standard temperature and pressure is 22.4 L.
- <em>The volume depends on the size of the container.</em> FALSE. The volume is constant at fixed moles, pressure and temperature.
- <em>The volume varies with the pressure.</em> FALSE. The standard pressure is 1 atm and it is constant.
Answer:
Saturated solution = 180 gram
Explanation:
Given:
Solubility of Z = 60 g / 100 g water
Given temperature = 20°C
Amount of water = 300 grams
Find:
Saturated solution
Computation:
Saturated solution = [Solubility of Z] × Amount of water
Saturated solution = [60 g / 100 g] × 300 grams
Saturated solution = [0.6] × 300 grams
Saturated solution = 180 gram
