Explanation: molarity = concentration c= n/V = 0.5 mol/ 0.05 l = 10 mol/l
Answer:
2.24 Liters are in 4.4 grams of CO2 at STP
Answer:
1.3 × 10³ cm³
Explanation:
The gas occupies a volume of V₁ = 310 cm³ under standard temperature and pressure (STP), that is, T₁ = 273.15 K and P₁ = 1.0 atm. In order to find the volume V₂ under different conditions we can use the combined gas law formula.

The greatest source of radiation is radon gas
