Which equation is used to calculate the weight of an object on a planet? w = mg w = mg w = startfraction mass over grams endfraction w = startfraction m over c endfraction

W = mg

Explanation:

Sorry if i get you right, we calculate weight by simply multiplying mass by the gravity on the surface of the planet.

Weight = Mass x Surface Gravity

W = m × g

So, if you know your weight on Earth

and the surface gravity on Earth, you

can calculate your mass. You can then

calculate your weight on any other

planet by using the surface gravity of

that planet in the same equation.

If you know the mass on like g = 9.81 m/s² for planet earth.

Goodluck

  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
