How many hydrogen atoms are present in 2.43 g of aspartame?
To find the number of hydrogen atoms in 2.43 g of aspartame, calculate the number of moles of aspartame using its molar mass. Aspartame has a molar mass of 294.3 g/mol. Then, determine the number of moles of hydrogen atoms in one molecule of aspartame (the chemical formula of aspartame is C14H18N2O5). Finally, multiply the number of moles of aspartame by the number of moles of hydrogen atoms to find the total number of hydrogen atoms in 2.43 g of aspartame.
What number of moles are present in 10.0 g aspartame?
To find the number of moles in 10.0 g of aspartame, we first need its molar mass. Aspartame has a molar mass of approximately 294.3 g/mol. Using the formula: moles = mass (g) / molar mass (g/mol), we calculate: moles = 10.0 g / 294.3 g/mol, which is approximately 0.034 moles of aspartame.
What number of atoms of nitrogen are in 1.2 g aspartame?
Aspartame (C14H18N2O5) contains two nitrogen atoms per molecule. To find the number of nitrogen atoms in 1.2 g of aspartame, we first calculate the molar mass of aspartame, which is approximately 294.3 g/mol. Then, we determine the number of moles in 1.2 g of aspartame (1.2 g / 294.3 g/mol ≈ 0.00407 moles). Since each mole of aspartame contains 2 moles of nitrogen atoms, this results in approximately 0.00814 moles of nitrogen atoms, or about 4.9 x 10^21 nitrogen atoms.
How many moles in 2.3 x 10-8 g of oxygen?
The answer is 7,18.10e-10 moles.
How many moles of platinum would be in 10.0 g of this metal?
10 g platinum is equal to 0,05 moles.
How many moles of carbon are present in 10 g?
To determine the number of moles in 10 g of carbon, you need to know the molar mass of carbon, which is approximately 12 g/mol. By dividing the given mass by the molar mass, you can calculate that there are approximately 0.83 moles of carbon in 10 g.
How many moles are there in 180gm of water?
10 moles of water (molar mass 18.0 g/mol) in 180 g, because 180 /18.0 = 10
How many hydrogen atoms are in one molecule of aspartame?
There are 17 micromoles in 5.00mg of aspartame. 5.00mg has a molecular weight of 294.303 g/mol. Aspartame is composed of carbon, hydrogen, nitrogen and oxygen. The chemical formula for aspartame is C14H18N2O5. The molar mass is 294.30 g mol−1. There are 6.022 x 10 ^23 molecules in a mole
How many molecules of aspartame are present in 2.50mg of aspartame?
The chemical formula for aspartame is C14H18N2O5. The molar mass is 294.30 g mol−1. If we have 2.50 mg of aspartame, we have 8.495 x 10^-6 mol of aspartame. There are 6.022 x 10 ^23 molecules in a mole so we have 5.116 x 10 ^18 aspartame molecules. There are 18 H atoms per aspartame molecule so there are 9.028 x 10^19 H atoms present in 2.50 mg of aspartame.
How many grams of NaCl are present in 10.00 moles?
10 moles of sodium chloride have 584,397 g.
How Many Moles Of PCl5 Can Be Produced From 58.0 G Of Cl2 (and Excess P4)?
To determine how many moles of PCl5 can be produced from 58.0 g of Cl2, we first need to calculate the moles of Cl2. The molar mass of Cl2 is approximately 70.9 g/mol, so the number of moles of Cl2 is 58.0 g / 70.9 g/mol ≈ 0.819 moles. The balanced reaction for the formation of PCl5 from P4 and Cl2 is: P4 + 10 Cl2 → 4 PCl5. From this, we see that 10 moles of Cl2 produce 4 moles of PCl5, so 0.819 moles of Cl2 can produce (0.819 moles Cl2) * (4 moles PCl5 / 10 moles Cl2) ≈ 0.3276 moles of PCl5. Thus, approximately 0.328 moles of PCl5 can be produced.
What is the molarity of a solution containing 15.0g of aspartame dissolved in water and the solution volume is brought to 250.00mL by adding water?
To find the molarity, first calculate the number of moles of aspartame. Given the molar mass of aspartame is 294.3 g/mol, you divide 15.0g by 294.3 g/mol to get 0.051 moles. Next, convert the solution volume to liters (250.00 mL = 0.250 L). Finally, divide the number of moles by the liters of solution to get the molarity, which is 0.204 M.
