just short of a mole. moles is mass/molar mass. mass is 42, molar mass is 44. 42/44
There are 1000 grams in one kilogram. Therefore, 42 kilograms is equal to 42 x 1000 = 42000 grams.
42 pounds is 19051g
42 kilograms = 92.6 pounds.
120000g = 264.55 pounds (rounded from 264.554715).
The average Aluminum can has a mass of roughly 14 grams. Then a Steel can has 2/3 more or 42 grams.
there is .42 moles
1.8 moles
The molar mass of sodium hydrogen carbonate is 84 grams per mole, therefore 0.5 moles of it weighs 42 grams.
As a rule of thumb, the atomic mass of an element equals the number of grams of that element equals a mole. Since the atomic mass of Nitrogen is 14, there are 14 grams in one mole of Nitrogen. Next, we just have to divide 42 by 14 and we get our answer: There are 2.9988 moles in 42 grams of Nitrogen.
42 grams is 1.48 ounces.
42 kilograms = 42000 grams (1 kilogram is 1000 grams)
42 grams of water is approximately 2.963 tablespoons.
1 kilogram = 1,000 grams 42 kilograms = 42,000 grams
There are 1000 grams in one kilogram. Therefore, 42 kilograms is equal to 42 x 1000 = 42000 grams.
First you need to write a balanced equation. You are given that propane undergoes a combustion reaction that produces carbon dioxide and water.Unbalanced: C3H8 + O2 ---> CO2 + H2OBalanced: C3H8 + 5O2 ---> 3CO2 + 4H2OGivens:42.0 grams C3H8 (Molecular mass 44.0 g)115.0 grams O2 (Molecular mass 32.0 g)Molecular mass of CO2: 44.0 gMole ratio 1:5:3:4 (C3H8:O2:CO2:H2O)Then you need to find which of the reactants are the limiting reactant (lowest value) and which is the excess reactant. The limiting reactant is what you will base the rest of the problem on. To do this, you convert each measurement to moles from grams.42.0 g C3H8 / (44.0 g) = .955 moles C3H8 115.0 g
42
According to this balanced equation:Na2O + H2O --> 2NaOH42 moles Na2O react with 42 moles H2O
