Dec 24 2016 We find the formula mass by multiplying each elements number of moles by its mole mass and adding them all up 286. The molar mass in terms of Atomic Mass units AMU is2AMU Na 1AMU C .
Feb 09 2021 To write the chemical formula of a hydrate write the number of water units per formula unit of compound after its chemical formula. The two chemical formulas are separated by a vertically centered dot. The hydrate of copperII sulfate has five water units associated with each formula unit so it is written as CuSO 4 •5H 2 O.
Read MoreMay 17 2021 Power Formula. If a device does a work W in time t then its power P is given by the formula P W t. We can calculate work W using the formula W F s. where F is the force applied. s is the displacement caused by the force along its direction. Thus the formula of power can also be written as. P W t F s t.
