Miguel learned about the difference between mass and weight. he wanted to investigate what he would weigh at different locations in our solar system. he used this table to organize data he found out about earth, the moon, neptune, and mercury. he needs to fill out the rest of the table. use the information in the table to calculate miguel’s weight, in pounds, on the moon, neptune, and mercury. explain the way you did your work.

The weight of an object is given by:

where m is the mass and g is the gravitational acceleration.

Miguel's mass is the same on every planet (m=60 kg), the only element changing in the formula is g, the value of the gravitational acceleration, which is different for every planet. So by knowing the ratio , where g is the gravitational acceleration on Earth and is the value of the gravitational acceleration on the planet we are studying, we can calculate the ratio , where W is Miguel's weight on Earth (which we know, it is W=132 lbs), and Wx is the weight on the planet we are studying:

- For the Moon, we have

so the weight on the Moon is

- For Neptune, we have

so the weight on Neptune is

- For Mercury, we have

so the weight on Mercury is

  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
