Acontainer holds a sample of hydrogen at 300 k with a pressure of 10 atm when the temperature decreased to 100k and volume remained constant. a. 3000 atm b. 3.3 atm c. 0.1 atm d. 0.3 atm me out will mark brainlest

Correct answers are D, A, A, B, A 

1) V1/T1=V2/T2 --> V2 = V1x(T2/T1) = 300cm³ x (333K/303K) = 330cm³ (assuming constant P) 

2) V1/T1=V2/T2 -->V1=V2x(T1/T2) = 1.0Lx(300K/100K) = 3.0L 

3) you have 2x as many moles of antacid ---> 2x as many moles of gas...V1/n1 = V2/n2 ---> V2 = V1 x (n2/n1).. double the moles, double the volume... so gas from 4 tablets > gas from 2 tablets. 

4) P1/T1=P2/T2 ---> P2=P1x(T2/T1)..if T was left in °C, P2=100kPax(10°C/60°C) = 17kPa. T MUST be in absolute temperature. either K or R. never °F nor °C. units of P do not matter. 

5).. constant T,n = boyles, constant P,n = charles, constant V,n = Gay-Lussac's

.3 m 3. 2. In an isothermal process, a mass of gas has its volume reduced from 50 cm3 to 32 cm3 . If the initial pressure of the gas is 80 kPa, determine its final  300. = 141 kPa. 2. A pressure vessel is subjected to a gas pressure of 8 atmospheres at a temperature of 15ºC. The vessel can withstand a maximum pressure of

10.063g / 10.00 ml = 1.0063 g/ml which rounds off to 4 sig figs as: 1.006 g/ml
