My brain hurts... Why do most mountains contain granitic rocks?
Granite is formed by slow cooling magma deep underground.
Granite is formed above ground but usually is buried by seismic waves during mountain formation.
Granite is formed by fast cooling magma deep underground.
Granitic is created by cooling lava on the surface and then buried during mountain formation.

Infants born with severe respiratory problems are sometimes given liquid ventilation: they breathe a liquid that can dissolve more oxygen than air can hold. one of these liquids is a fluorinated compound, cf3(cf2)7br. the solubility of oxygen in this liquid is 66 mlo2 per 100 ml liquid. in contrast, air is 21 % oxygen by volume. calculate the moles of o2 present in an infant's lungs (volume: 12 ml ) if the infant takes a full breath of air. assume a pressure of 1 atm in the lungs.
