A4.00 l flexible container holds a sample of hydrogen gas at 153 kpa. if the pressure increases to 203 kpa and the temperature remains constant . what will the volume be ?
0.33 l
2.26 l
3.02 l

3.02L

Step-by-step explanation:

We would be applying Boyle Law to this question.

Boyle's Law states that volume of a gas at a constant temperature is inversely proportional to the applied pressure when the temperature and mass remains constant.

Mathematically Boyle's law =

P₁V₁=P₂V₂

From the question ,

P₁ = 153kpa

V₁ = 4.00L

P₂ = 203kpa

V₂ = unknown

Therefore,

153kpa × 4.00L = 203kpa × V₂

612 = 203V₂

V₂= 612 ÷ 203

V₂ = 3.02L

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies
