One mole of anything is 6.022 x 1023 everythings, including molecules. To determine the number of molecules in a given number of moles, multiply the moles by 6.022 x 1023. The chemical formula of sucrose is C12H22O11.
2.5 mol C12H22O11 x (6.022 x 1023 molecules C12H22O11 )/(1 mol C12H22O11 ) = 1.5 x 1024 molecules C12H22O11 (rounded to two significant figures)
The molarity can be calculated using the formula: moles of solute divided by liters of solution. In this case, the moles of sucrose is 25, and the liters of solution is 50. This gives a molarity of 0.5 M.
The answer is 64,9 moles.
For every mole of C3H8 that reacts, 4 moles of water are formed. Therefore, 5.0 moles of C3H8 will form 5.0 x 4 = 20 moles of water. To convert moles to molecules, you would then multiply by Avogadro's number (6.022 x 10^23 molecules/mol). So, 20 moles of water would equal 20 x 6.022 x 10^23 = 1.2044 x 10^25 molecules of water.
The answer is 88 moles.
To find the number of moles from a given number of particles, you can use Avogadro's number, which is approximately (6.022 \times 10^{23}) particles per mole. To calculate the number of moles in (5.66 \times 10^{25}) lithium ions, divide the number of ions by Avogadro's number: [ \text{Moles} = \frac{5.66 \times 10^{25}}{6.022 \times 10^{23}} \approx 94.0 \text{ moles} ] So, (5.66 \times 10^{25}) lithium ions equal approximately 94.0 moles.
The molarity can be calculated using the formula: moles of solute divided by liters of solution. In this case, the moles of sucrose is 25, and the liters of solution is 50. This gives a molarity of 0.5 M.
To find the number of moles, divide the number of molecules by Avogadro's number (6.022 x 10^23 molecules/mol). In this case, 2.0 x 10^25 molecules of silver nitrate is equal to 33.2 moles (2.0 x 10^25 / 6.022 x 10^23).
To find the number of moles in 4.06 x 10^25 molecules of sodium fluoride, you would divide the number of molecules by Avogadro's number, which is approximately 6.022 x 10^23 molecules/mol. Therefore, 4.06 x 10^25 molecules / 6.022 x 10^23 molecules/mol ≈ 67.5 moles of sodium fluoride.
If you meant 1.5*10^23 and not 1.51023 molecules, see below:1.5*10^23 molecules / (6.022*10^23 molecules/mol)= 1.5/6.022 mol=.25 moles, rounded to two significant figures.
A number of atoms/molecules in a given number of moles is regardless of the substance unless it deals with stoicheometry. One mole represents a number of Avogadro's constant, approximately 6.022 x 10^23. Therefore there are 1.91 x 10^25 molecules of water in 31.8 moles.
To find the number of molecules in 25g of MgSO4, you need to first calculate the number of moles of MgSO4 using its molar mass (120.37 g/mol). Then, you can use Avogadro's number (6.022 x 10^23 molecules/mol) to convert moles to molecules.
The answer is 64,9 moles.
For every mole of C3H8 that reacts, 4 moles of water are formed. Therefore, 5.0 moles of C3H8 will form 5.0 x 4 = 20 moles of water. To convert moles to molecules, you would then multiply by Avogadro's number (6.022 x 10^23 molecules/mol). So, 20 moles of water would equal 20 x 6.022 x 10^23 = 1.2044 x 10^25 molecules of water.
The chemical formula for ethane is C2H6 and there is 6.022 * 10^23 molecules in every mole. So to find your answer simply multiply 6.022 * 10^23 by 51.2 which gives: 3.083 X 10^25
The answer is 88 moles.
To find the mass in grams of 1.20x10^25 molecules of ammonia (NH3), you first calculate the molar mass of NH3 (17.031 g/mol). Then, divide the given number of molecules by Avogadro's number (6.022x10^23 molecules/mol) to find the number of moles, and finally, multiply the number of moles by the molar mass to get the mass in grams, which will be approximately 4.08x10^2 grams.
To calculate the number of molecules in 21.6 grams of CH4, you need to first determine the molar mass of CH4 (methane). The molar mass of CH4 is approximately 16 g/mol. Next, divide the given mass (21.6 g) by the molar mass to get the number of moles. Finally, use Avogadro's number (6.022 x 10^23 molecules/mol) to convert moles to molecules.
