Answer:
Density measures the amount of mass per unit of volume in a substance. Concentration describes the amount of a substance dissolved in another substance. Changing the concentration of a solution changes the density of the solution.
Answer:
278 balloons can be aired.
Explanation:
We apply the Ideal Gases Law to determine the total available volume for each baloon of 0.75L. So we need to divide the volume we obtain by the volume of each baloon.
We determine the moles of CO₂
375 g. 1 mol / 44g = 8.52 moles
V = (n . R . T) / P → (8.52 mol . 0.082 . 298K) / 1 atm = 208.3 L
That's the total volume from the tank, so we can inflate (208.3 / 0.75) = at least 278 balloons
