Answer:
The answer to your question is V2 = 1.3 l
Explanation:
Data
Pressure 1 = P1 = 1.5 atm
Volume 1 = V1 = 2.50 l
Temperature 1 = T1 = 22°C
Pressure 2 = P2 = 3 atm
Volume 2 = V2 = ?
Temperature 2 = T2 = 35°C
Process
1.- Convert temperature to °K
T1 = 22 + 273 = 295°K
T2 = 35 + 273 = 308°K
2.- Use the combine gas law to solve this problem
P1V1/T1 = P2V2/T2
-Solve for V2
V2 = P1V1T2 / T1P2
3.- Substitution
V2 = (1.5 x 2.5 x 308) / (295 x 3)
4.- Simplification
V2 = 1155 / 885
5.- Result
V2 = 1.3 l
Answer:
43.2 g of table salt occupies 20.0 cm2of space- Appropriate for calculating density
150 g of iron density of iron 79.0 g/cm3- Appropriate for calculating volume
21.0 mL of methanol density of methanol 0.79g/mL - Appropriate for calculating mass
3.00 g of white pine, density of white pine 0.40 g/cm3- Appropriate for calculating volume
5.00 cm,3 of table salt weighs 10.8g-Appropriate for calculating density
Explanation:
Density is defined as mass per unit volume. Hence in science;
Density= mass/volume
When mass and volume are both given, the information can be used to determine the density of a given substance.
When volume and density are both given, the information can be used to determine the mass of a given substance.
When the mass and density of a substance are both given, the information can be used to determine the volume of the substance.
Hence the answers given above.

Explanation:
If you are given atoms you need to divide by Avogadro's number 6.022x10^23
then you will have moles of sulfur-- once you have moles multiply by the molar mass of sulfur to go from moles to grams
mm of sulfur is 32 g/mol
