A minibus had 23 passengers at the beginning of a journey. twelve passengers alighted at the first stop while 9 boarded six of those who boatded at the first stop alighted at the second stop and 12 got in .the minibus should not stop again up to the final destination .the charges from the starting point were $50 up to the first stop ,$70 up to the second stop and $85 up to the final destination. how many passengers alighted at the final destination. how many passengers were ferried by the minibus through the journey. how much money was collected during the trip. maths question

  1.the balanced   chemical equation is as below

cu +   2 ag(no)₃ → cu(no₃)₂   +2 ag

2.the   much silver   produced   is   50.9 g

step 1: find the   moles of cu

moles =   mass÷   molar mass

  from periodic table the molar mass of cu = 63.5 g/mol

moles is therefore = 15.00 g÷ 63.5 g/mol = 0.236   moles

step 2: use the mole ratio to determine the   moles of ag

from equation above   cu: ag   is 1: 2

therefore the moles of ag   =0.236   moles   x 2/1 =0.472   moles

step 3: find the mass   of ag

mass = moles x molar mass

from periodic table   the molar mass of ag =107.87 g/mol

mass   = 0.472   moles x 107.87 g/mol = 50.9 g

3.   the   much   silver   collected worth is   1.797 oz

  convert   50.9 g   to oz

that is   1 gram = 0.0353 oz

          50.9 grams =?   oz

by cross multiplication

={(50.9 grams x 0.0353 oz) / 1   gram}   =1.797 oz

real, smaller and upside-down.   so the answer should be b.

force tends to be low and long diustance masses are high

pretty sure it's false
