What is the final pressure, in mmHg, for a gas in an aerosol can at an initial pressure of 1.40 atm at 12°C which is heated to 3

liubo4ka [24]

Answer:

b. 1150 mmHg

General Formulas and Concepts:

Chemistry - Gas Laws

Gay Lussac Law - $\frac{P_1}{T_1} =\frac{P_2}{T_2}$

P₁ is Pressure 1
T₁ is Temperature 1 in Kelvin
P₂ is Pressure 2
T₂ is Temperature 2 in Kelvin

Explanation:

Step 1: Define

P₁ = 1.40 atm

T₁ = 12°C

P₂ = unknown

T₂ = 35°C

Step 2: Identify Conversions

1 atm = 760 mmHg

K = °C + 273.15

Step 3: Convert

P₁ = 1.40 atm = 1064 mmHg

T₁ = 12°C = 285.15 K

T₂ = 35°C = 308.15 K

Step 4: Find P₂

Substitute: $\frac{1064 \ mmHg}{285.15 \ K} =\frac{P_2}{308.15 \ K}$
Cross-multiply: $(1064 \ mmHg)(308.15 \ K)=P_2(285.15 \ K)$
Multiply: $327872 \ mmHg \cdot K=P_2(285.15 \ K)$
Isolate P₂: $\frac{327872 \ mmHg \cdot K}{285.15 \ K}=P_2$
Divide: $1149.82 \ mmHg=P_2$
Rewrite: $P_2=1149.82 \ mmHg$

Step 5: Check

We are given 3 sig figs. Follow sig fig rules and round.

1149.82 mmHg ≈ 1150 mmHg

How many grams of H20 will be produced by 18g H2

AURORKA [14]

Answer:

160.86 g to the nearest hundredth.

Explanation:

H2 + O ---> H2O

2.016 g H2 produces 18.016 g H2O

1g .. .. .. .. .. 18.016 / 2.016 g H2O

18g .. .. .. .. .. . . (18.016 * 18) / 2.016 g H2O.

= 160.86 g.

A 2.16-g sample of an oxide of chromium contains 1.34 g of chromium. Calculate the simplest formula for the compound.

fomenos

Answer:

chromium:oxygen=1:2

Explanation:

total mass=2.16g

mass of chromium=1.34g

mass of oxygen=2.16g-1.34g=0.82g

chromium oxygen

mass:1.34g 0.82

RAM:52 16

divide the mass with the RAM

0.02577 0.05125

divide by smallest number to find ratio

1 2

ratio of chromium to oxygen=1:2
