SpyIntel [72]
Answer: C(s) + O2(g) --> CO2(g)12g (C) .... 50.8g (O2)................. initial amounts0g(C) .........18.8g(O2) ................. amounts when reaction completeThat means that C was the limiting reactant, and the amount of CO2 is based on the amount of carbon that burned. Covert 12 grams of carbon to moles. The moles of CO2 will be the same, since they are in a 1:1 mole ratio. Then convert the moles of CO2 to grams.12g C x (1 mol C / 12.0 g C) x (1 mol CO2 / 1 mol C) x (44.0g CO2 / 1 mol CO2) =44 g of CO2

The mass of a large order of french fries is about 170 G what is its approximate weight in pounds
kap26 [50]

Answer:

             0.374 Pound Approximately

Solution:

Gram and Pound are related as,

1 Gram  =  0.0022 Pound (approximately)

As we are given with 170 g of French Fries, so it can be converted into pounds as,

          1 Gram  =  0.0022 Pound

So,

          170 Grams  =  X Pounds

Solving for X,

                      X =  (170 Gram × 0.0022 Pounds) ÷ 1 Gram

                      X =  0.374 Pound Approximately
