define the following write the units and formula
It depends on the substance and its molar mass.In order to convert from grams to formula units, you must first convert grams to moles, then moles to formula units (grams --> moles --> formula units).1. Divide the mass (g) of the given substance by the substance's molar mass.2. Multiply the number of moles found in Step 1 (above) by Avogadro's number (6.022 x 1023).---- Mass substance ----- X 6.022 x 1023 formula unitsMolar mass substanceCONVERSION FACTOR47.63g substance x 1 mol substance ---- x ----- Avogadro's number///////////////////// molar mass (g) substance ////// 1 mol substance
The formula for energy. E is for energy(Units = Joules) P is for power(Units = Watts) T is for time(Units = Seconds)
Formula for calculating the volume of a cylinder = pi*radius2*length giving your answer in cubic units. Therefore: pi*42*9 = 452.3893421 cubic units. To the nearest whole number: 452 cubic units.
Density = Mass/Volume. Conversion between units will depend on what the two units are.
42.394 grams.
The number of formula units is 0,602 214 085 7.10e23.
To find the number of formula units of magnesium oxide in 5.68 moles, you first need to determine the formula of magnesium oxide (MgO). Then use Avogadro's number (6.022 x 10^23) to convert moles to formula units. So, in 5.68 moles of MgO, there are approximately 3.43 x 10^24 formula units.
Amylose is a polymer of α-D-glucose units so the exact formula is variable depending on the number of glucose units. It consequently has a general formula of (C6H12O5)n. where n is the number of repeated units
To determine the number of formula units in a salt crystal, you need to know the molar mass of the salt. Once you know the molar mass, you can use it to calculate the number of moles present in the crystal, and then convert that to the number of formula units using Avogadro's number, which is 6.022 x 10^23 formula units/mol.
0.688 moles*6.02x1023=4.14x1023 Formula units
The maximum number of formula units of NaCl in one mole is 6.022 x 10^23, which is Avogadro's number. This means that in one mole of NaCl, there are 6.022 x 10^23 formula units of NaCl.
The number of formula units of NaCl is 11335.10e17.
This question needs clarification, because "formula units" can mean either the number of atoms to constitute one formula or Avogadro's Number of such formula units, although the latter should more precisely described as "gram formula units".
The chemical formula for polydimethylsiloxanes is (C2H6OSi)n, where n represents the number of repeating units in the polymer chain.
To calculate the number of moles, first find the molar mass of CaCl2 (40.08 g/mol for Ca + 2 * 35.45 g/mol for Cl). Then divide the given number of formula units by Avogadro's number (6.022 x 10^23 formula units/mol) to get the number of moles.
There are 5.25 x 10^22 formula units in 0.87 moles of sodium acetate. This is determined by multiplying the Avogadro's number (6.022 x 10^23 formula units/mole) by the number of moles.
