What is an oblong number?
An oblong number is a composite (non-prime) number. If p and q are a factor-pair for an oblong number n, then the number n can be represented by a rectangle or oblong that is p units x q units.
How many formula units in 47.63 grams?
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
What metric units are represented by points on the plotted line?
Any metric or non-metric units can be represented by points on the plotted line.
How can you absolute value to represent a negative number in a real-world situation?
If your bank account is overdrawn by 5 units then your statement will show the balance as -5. So the negative number, -5, is represented as a debt of 5 units of currency (an absolute number).
What do you need to change moles to number of particles?
You need to know that one mole is 6.022 x 1023 particles (atoms, molecules, ions, formula units, etc...).
What does a coefficient represent in a chemical formula?
It represents the amount of the substance. It can mean the number of atoms, molecules, formula units, or moles.
How is molarity expressed?
Molarity is expressed in moles per litre of solution.
How many moles of CaCl2 are in 2.00 1024 formula units?
To find the number of moles of CaCl2 in 2.00x10^24 formula units, you need to first determine the molar mass of CaCl2, which is 110.98 g/mol. Then, divide the number of formula units by Avogadro's number (6.022x10^23) to convert to moles. This gives you approximately 3.32 moles of CaCl2.
What is the volume occupied by 2.12 moles of NO?
The volume occupied by 2.12 moles of nitrous oxide is 9.35. A mole is described in chemistry as an amount of pure substance containing the same number of chemical units as there are atoms.
Determine the number of formula units that are in 0.688 moles of AgNO3?
0.688 moles*6.02x1023=4.14x1023 Formula units
What does stoichiometry use to relate miles of one molecule to moles of another?
Stoichiometry uses the molar ratios from the balanced chemical equation to relate the number of miles of one molecule to moles of another molecule. These ratios are used to convert between different units (miles to moles) during chemical calculations.
What is the number of moles of sodium hydroxide NaOH corresponding to 10.84 and times 1023 formula units of NaOH?
To find the number of moles of NaOH, you need to divide the given number of formula units by Avogadro's number (6.022 x 10^23). Therefore, the number of moles of NaOH is 10.84/6.022 ≈ 1.8 x 10^-23 moles.
How many formula units of LiCl are equal to .648 moles?
42.394 grams.
How many formula units of sodium acetate are in 0.87 moles of sodium acetate?
How many formula units of sodium acetate are in 0.87 moles of sodium acetat
How many formula units are there in 2.45 moles potassium chloride?
To determine the number of formula units in 2.45 moles of potassium chloride, you first need to find the molar mass of KCl, which is approximately 74.55 g/mol. Then, divide the number of moles by the molar mass to get the number of formula units. Therefore, 2.45 moles of KCl is equivalent to about 163 formula units.
What is the number of formula units that are in 5.68 moles of magnesium oxide?
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.
What chemical equation represents a formation of Teflon polymer from two monomers units?
The formation of Teflon polymer from two monomer units, tetrafluoroethylene, can be represented by the following chemical equation: nCF2=CF2 --> [(CF2-CF2)n] where n represents the number of repeating units in the polymer chain.
