5.988 kg = 5988 g. As you already know how the grams to moles conversion works, find the number of moles: n = 5988 g / 18.015 g/mol = 332.4 mol. You can always use our grams to moles calculator to check the result! Knowing how to convert grams to moles may be helpful in numerous chemical tasks, e.g., finding the mole fraction of a solution.
Jan 30, 2023 · In this example, multiply the grams of Na by the conversion factor 1 mol Na/ 22.98 g Na, with 22.98g being the molar mass of one mole of Na, which then allows cancelation of grams, leaving moles of Na.
Dec 16, 2019 · \(\mathrm{70.0\: kg\times\dfrac{1,000\: g}{1\: kg}=7.00\times10^4\: g}\) Now we determine the amount of Co: \(\mathrm{7.00\times10^4\: g\: solution\times\dfrac{21\: g\: Co}{1,000,000,000\: g\: solution}=0.0015\: g\: Co}\) This is only 1.5 mg.

Steps for Problem Solving. Example 16.5.1 16.5. 1. Use the activity series to predict if the reaction below will occur. If not, write NR NR. If the reaction does occur, write the products of the reaction and balance the equation. \ceAl(s) + \ceZn(NO3)2(aq) → \ce A l ( s) + \ce Z n ( N O 3) 2 ( a q) →.
Certain systems, such as the SI system of units, have different units for describing the same features, such as the meter and millimeter, which are both units of distance. If a measurement is given in one unit, it can be converted into another unit describing the same property, such as length. A conversion factor can be used, such as a meter being 1000 times more than a millimeter ...
Knowing the density of the acid to be 1.413 g/mL, we can calculate the weight of 1 L of 70% HNO 3 to be 1413 grams. Knowing that the solution is 70 wt % would then allow the number of grams of HNO 3 to be calculated: (0.700)(1413g) = 989.1 grams HNO 3 per liter.
