x moles H2O = (1 mole H2O/18 grams H2O) x (600 grams H2O) Step 3 Solve the equation in Step 2 to find that there are 3.33 moles of H2O in 600 grams of H2O. References Stoichiometry How to calculate the molar masses of chemical compoundsCite This Article MLA Tyler, Judy. "How To...
\table[[mol How many moles ofAlare necessary to form86.8gofAlBr3from this reaction:2Al(s)+3Br2(l)→2AlBr3(s)? \table[[mol There are 2 steps to solve this one.
Express this as moles per kilogram solution. Now, you have 250 ml of water, which is about 250 g of water (assuming a density of 1 g/ml), but you also have 3 grams of solute, so the total mass of the solution is closer to 253 grams than 250. Using 2 significant figures, it's...
How to Treat Vole Damage When to Call in the Pros What are Voles? Not to be confused with moles, voles are rodents but they are neither blind nor deaf. Also dubbed “meadow mice” and “field mice” (although the latter is a totally different animal), voles feed on plants, while mole...
To solve the problem, workers first built an enormous dry dock on the South Boston side of the channel. Known as the casting basin, the dry dock measured 1,000 feet long, 300 feet wide and 60 feet deep -- big enough to construct the six concrete sections that would make up the ...
The molar solubility is the number of moles that can be dissolved per liter of a solution until the solution becomes saturated. A saturated solution is a solution in which the maximum amount of solute has been dissolved. An unsaturated solution is a solu
