The moles that are present in 150 g of ammonium hydrogen phosphite is 1.136 moles
<u><em>calculation</em></u>
<em>The formula of ammonium hydrogen phosphite = (NH4)2HPO4</em>
moles = mass/molar mass
mass= 150 g
molar mass of (NH4)2HPO4 = [ ( 14+ 1x4)2) +1 + 31 + ( 4 x16)] =132 g/mol
moles is therefore = 150 g/ 132 g/mol =1.136 moles
Volume is mass divided by density or mass/density.
so 244/2.70
is equal to 90.3703703704 which is the volume
<span>If a lever has a constant force applied at 90∘ to the lever arm at a fixed distance from the pivot point (point of rotation), the torque on the lever is given by Torque = force (at 90∘ to lever arm) × distance to pivot point
Force should be perpendicular to the lever arm
Therefore; you would do 15N X 2.0 m = 30 Nm or 30Joules</span>
