Write the ka expression for an aqueous solution of nitrous acid:

In pqr m< p=60 m< q= 30 and m

Ican determine the molar mass of an element by looking on the under the atomic mass for the element. for example the molar mass of phosphorus is 30.974 grams/mole. avogadro’s number tells me the amount of representative particles in 1 mole of any substance. this means 12.011 gram sample of carbon and a 32.0 gram sample of sulfur have the same number of atoms.

How does the viscosity of magma change as magma cools?
