May 20, 2018 · Use chemical formulas as conversion factors. Figure 6.5.1 6.5. 1 shows that we need 2 hydrogen atoms and 1 oxygen atom to make one water molecule. If we want to make two water molecules, we will need 4 hydrogen atoms and 2 oxygen atoms. If we want to make five molecules of water, we need 10 hydrogen atoms and 5 oxygen atoms.
Jun 16, 2023 · V = m × conversion factor. Since the mass is in grams, we need to get rid of these units and replace them with volume units. This can be done if the reciprocal of the density is used as a conversion factor. This puts grams in the denominator so that these units cancel: V = m × 1 ρ = 98.0 g × 1 cm3 13.6 g = 7.21 cm3.
Sep 15, 2022 · Dimensional analysis (unit conversions) involves the use of conversion factors that will cancel unwanted units and produce the appropriate units. 2.6: Problem Solving and Unit Conversions is shared under a license and was authored, remixed, and/or curated by Marisa Alviar-Agnew & Henry Agnew.

The balanced chemical equation is as follows: 2FeCl 3 (aq) + 3Na 2 C 2 O 4 (aq) → Fe 2 (C 2 O 4) 3 (s) + 6NaCl (aq) Solution. First we need to determine the number of moles of Na 2 C 2 O 4 that reacted. We will convert the volume to litres and then use the concentration of the solution as a conversion factor:

We will convert the volume to liters and then use the concentration of the solution as a conversion factor: 9.04 mL × (1 L / 1,000 mL) × (0.1074 mol Na 2 C 2 O 4 / L) = 0.000971 mol Na 2 C 2 O 4. Now we will use the balanced chemical equation to determine the number of moles of Fe 3+ (aq) that were present in the initial aliquot:
