As Molarity is given by,
Molarity = moles / volume ------(1)
Data Given:
mass of water = 5 Kg = 5000 g
moles = 5 moles
Solution:
As we know that volume is related to mass as,
Volume = mass / density
Putting values,
Volume = 5000 g / 1 g/cm³
V = 5000 cm³
Now, Putting value of volume and moles in eq. 1,
M = 5 mol / 5000 cm³
M = 0.0001 mol/cm³
or,
M = 1 mol/dm³
82% of drinking water supplies in Ireland are sourced from surface water (rivers and lakes) and 18% comes from groundwater - it depends where you live (quick g00gle search should answer you question)
That would be the cobalt(11) Chloride Hexahydrate
Answer:
457.5kPa
Explanation:
Given data
V1=V2=350mL (<em>fixed volume</em> )
P1=366kPa
T1= 88 degrees Celsius
P2=??
T2= 110 degrees Celsius
For the general gas equation
P1V1/T1= P2V2/T2
V1=V2
P1/T1= P2/T2
Substitute
366/88= P2/110
Cross multiply we have
P2*88=366*110
P2*88= 40260
P2= 40260/88
P2= 457.5 kPa
Hence the pressure will change to 457.5kPa
