Hydrochloric acid is usually purchased in a concentrated form that is 37.0% HCl by mass and has a density of 1.20g/mL. Calculate the molarity of the concd HCl.
1.20 g/mL x 1000 mL x 0.37 x (1/36.5) = about 12 M or so but you do it exactly.
Then mL x M = mL x M
mL x 12 M = 2800 mL x 0.475
Solve for mL of the concd HCl solution.
The volume occupied by the gas in the container is 1 m³
Boyles law applies
P₁ V₁ = P₂ V₂
Where P₁ = 200kpa
P₂ = 300kpa
if its initial volume is 1.5
then,
P₁ V₁ = P₂ V₂
200 × 1.5 = 300 × V₂
V₂ = 200 × 1.5 / 300
= 1 m³
Hence the volume occupied by the gas container is 1 m³

Explanation:
Na2 SO4 is the chemical identity. You can count the number of atoms just by looking
Answer:
Freezing point = 1.25
Explanation:
If we increase the concentration of the solution, the concentration of H+ does not change.
Convert 2.5% in to decimal
2.5% = 2.5 ÷100
= 0.025
The freezing point = 0.025 × 50
= 1.25
Answer: I found this online. Hope it helps you.
Explanation:
This pressure is transmitted throughout the liquid and makes it more difficult for bubbles to form and for boiling to take place. If the pressure is reduced, the liquid requires less energy to change to a gaseous phase, and boiling occurs at a lower temperature.
