If 456 dm3 of krypton at 101 kPa and 21°C is compressed into a 27.0 dm3 tank at the same temperature, what is the pressure of krypton in the tank?
As at same temperature , P1 × V1 = P2 × V2Where P1 and P2 are initial and final pressures respectively and V1 and V2 are initial and final volumes...

A bacteria triples every 15 minutes. If there were originally 45 cultures in the lab, write the exponential function then determine how many cultures there are after 5 hours.
For every hour, the bacteria multiple by 4t periodsThe exponential function for number of cultures after t hours = 45 × 34tNumber of culture after 5 hours = 45 ×...

The combustion of methane gas is described by the equation CH4+2O2→CO2+2H2O.
What volume of oxygen is needed at STP to combust 4.7 L methane?
How much carbon dioxide will be formed?
CH4+2O2→CO2+2H2O V(O_2 ):V(CH_4 )=2:1 V(O_2)=V(CH_4 )×2=4.7×2=9.4 L V(CO_2 ):V(CH_4 )=1:1 V(CO_2)=V(CH_4 )=4.7 L Answer: V(O2) = 9.4 L, V(CO2) = 4.7 L.

A 40.8 mol sample of methane gas CH4(g) is placed in a 1020 L container at 298 K. What is the pressure, in atm of the methane gas?
ollowing the Ideal gas law: pV=nRT where R is gas constant and equal to 0.0821 L·atm·K-1·mol-1 For this case, pressure in atm have been equal to: p=nRTV=40.8 (mol)∙0.0821 (L∙atm∙K-1∙mol-1)∙298 (K)/...

A 40.8 mol sample of methane gas CH4 is places in a 1020 L container at 298K.
What is the pressure, in atm of the methane gas?
Use the ideal gas law. From original equation PV=nRT there is P=nRT/V, R=8.31441J/(K∙mol)=0.08206(L∙atm)/(K∙mol), i.e. P (atm) = (40.8 mol*0.08206(L∙atm)/(K∙mol)*298K)/1020 L = 0.9782 atm Answer: 0.9782 atm
