Protons have a positive charge. The answer is C.
Answer:
P₂ = 1.05 atm
Explanation:
Given data:
Initial temperature = 24.0 °C (24+273 = 297 K)
Initial pressure = 0.900 atm
Final pressure = ?
Final temperature = 75 °C (75 + 273 =348 K)
Volume = constant
Solution:
According to Gay-Lussac Law,
The pressure of given amount of a gas is directly proportional to its temperature at constant volume and number of moles.
Mathematical relationship:
P₁/T₁ = P₂/T₂
Now we will put the values in formula:
0.900 atm / 297 K = P₂/348 K
P₂ = 0.900 atm × 348 K / 297 K
P₂ = 313.2 atm. K /297 K
P₂ = 1.05 atm
Answer: “Formaldehyde” is emitted from most manufactured building materials and furniture.
Answer:
The molar mass of the gas
Explanation:
The ideal gas equation of state is:
PV = nRT
If we measure the volume (V), the pressure (P), and the temperature (T), we use the gas constant R (0.082 L.atm/K.mol) to calculate n (moles of gas):
n = PV/RT
Then, we can divide the mass into the number of moles to calculate the molar mass of the gas:
molar mass = mass/n
