calculate the volume od a CO2 cartridge that has a pressure of 850 PSI at a temperature of 21ºc the cartridge contains 0.273 mol
gladu [14]
Answer is: volume of CO₂ is 0,113 dm³.
Ideal gas law = pV = nRT.
p = 850 PSI = 5860543,6992 Pa.
Psi <span>is the abbreviation of pound per square inch.
T = 21</span>°C = 294,15 K.
n = 0,273 mol.
R = 8,314 J/K·mol.
V = nRT ÷ p
V = 0,273 mol · 8,314 J/K·mol · 294,15 K ÷ 5860543,6992 Pa.
V = 0,00011 m³ = 0,113 dm³.

What volume of lead (of density 11.3 g/cm3) has the same mass as 330 cm3 of a piece of redwood (of density 0.38 g/cm3)?
zimovet [89]

Answer:

The sample of lead has a volume of 11.1 cm³

Explanation:

<u>Step 1:</u> Data given

x cm³ lead has a density of 11.3 g/cm³

it has the same mass as 330cm³ of a piece of redwood with density 0.38g/cm³

<u>Step 2</u>: Calculate mass of the piece of redwood

Density = mass/volume

mass = density * volume

Mass of the piece of redwood = 0.38 g/cm³ * 330cm³ = 125.4 grams

Since the sample of lead has the same mass, it also has a mass of 125.4 grams

<u>Step 3</u>: Calculate volume of the lead

Density = mass/ volume

Volume = mass/ density

Volume of lead = 125.4g / 11.3g/cm³ = 11.097 cm³≈11.1 cm³

The sample of lead has a volume of 11.1 cm³

When hot lava reaches seawater, the salts in the water react with steam to form gaseous hydrochloric acid. You are given an unba
qaws [65]
Cl⁻ + H₂O(g) = HCl(g) + OH⁻

w - it is percent chloride ions in solid sea salt (as a rule 55%)

m - it is the mass of sea salt

m(Cl⁻)=mw/100

m(Cl⁻)/M(Cl)=V(HCl)/V₀

mw/{100M(Cl)}=V(HCl)/V₀

m=100M(Cl)V(HCl)/{wV₀}  (<span>the mass of solid sea salt)</span>

V₀=22.4 L/mol
M(Cl)=35.45 g/mol

for example:
V(HCl)= 1.0 L
w=55%

m=100×35.45×1.0/{55×22.4}=2.88 g
