True, Crude oil is a type of liquid thereofre can flow through the pourus layer but seeming how impermeable means to not allow fluid to pass it would only make sense that the fluid is trapped between the two.
Answer:
Plutonium is the second transuranium element of the actinide series.
Answer: 50 nm
Explanation: Two steps:
1. Divide 3.25/6.5 = 0.5
2. Divide 10^8/10^6 = 10^2
nm^2/nm = nm
Combine: 0.5x10^2 nm
or 50 nm
Answer:
547.5g
Explanation:
To get the mass, you need moles.
moles = (molarity)(Liters)
moles = (1.230M)(4.200L) = 5.166 moles Na2CO3
Now, just use stoichiometry
molar mass of Na2CO3 = 2(mass of Na) + (mass of C) + 3(mass of O)
= 2(22.9) + 12.01 + 3(16) = 105.99g/mol
5.166moles(105.99g/mol)
= 547.544
But, the measurements given had 4 significant figures, so in chemistry we write:
547.5g
