There's no formula. It's 6.02 x 10^23.
Avogadro's number.
That's what defines a mole, 6.02 x 10^23 atoms of any particular substance.
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.
To find the number of hydrogen atoms in 2 grams of cholesterol, you need to first calculate the molar mass of cholesterol (about 386 g/mol) and then divide the given mass by the molar mass to find the number of moles. Next, use the molecular formula of cholesterol (C27H46O) to determine the number of hydrogen atoms in one mole of cholesterol. Finally, multiply this number by the number of moles to find the total number of hydrogen atoms present in 2 grams of cholesterol.
To calculate the number of hydrogen atoms in 167 grams of propane (C3H8), first calculate the molar mass of propane (3 carbon atoms x 12.01 g/mol + 8 hydrogen atoms x 1.008 g/mol) = 44.1 g/mol. Next, use the formula: number of moles = mass / molar mass (167 g / 44.1 g/mol ≈ 3.79 mol). Since there are 8 hydrogen atoms per molecule of propane, multiply the number of moles by Avogadro's number (6.022 x 10^23) to find the total number of hydrogen atoms. The result is approximately 2.28 x 10^24 hydrogen atoms.

Find the molar mass of urea (CH4N2O) by adding the atomic masses of carbon, hydrogen, oxygen, and nitrogen. Then, divide the given mass of urea (5.6g) by the molar mass to find the number of moles. Finally, use the subscripts in the chemical formula to determine the number of atoms of each element in one mole of urea.
To find the number of hydrogen atoms in 90 amu of ethane (C2H6), use the molar mass of ethane to determine the number of moles present. Next, use the molecular formula of ethane to calculate the number of hydrogen atoms in one mole, and then multiply by the number of moles present to find the total number of hydrogen atoms.
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.
To find the number of atoms of hydrogen in a compound, you need to look at the chemical formula. In carbon hydroxide (CHO), there are 1 atom of hydrogen for each carbon and oxygen atom. In this case, there are 0.180 moles of CHO, so there are 0.180 moles of hydrogen atoms as well. To convert moles to atoms, you can use Avogadro's number (6.022 x 10^23) to find that there are approximately 1.08 x 10^23 atoms of hydrogen in 0.180 moles of carbon hydroxide.
You can figure this question out by looking up quinine to find its chemical formula. The number of moles of hydrogen will be the number of hydrogen in the chemical formula. Once you see the chemical formula is C20H24N2O2 then you know that there are 24 moles of hydrogen for every one mole of quinine.
The formula unit for ammonium sulfide has the formula (NH4)2S. This formula shows that the formula unit contains two ammonium ions, each of which contains four hydrogen atoms. The total number of hydrogen atoms is therefore 8.
There are 8 atoms of hydrogen in each mole of C3H8O3 therefore, there are 8 x 0.05 moles in 0.05 moles of C3H8O3. Which is 0.4 moles Using Avogadro's number, there are 6.022 x10^23 atoms per mol that is the same as 0.4 x 6.022 x10^23 = 2.41 x 10^23.
To find the empirical formula, we first need to convert the mass of CO2 and H2O to moles. From the molar ratios in the products, we find the moles of carbon and hydrogen present. Then, we determine the ratio of carbon to hydrogen atoms, giving the empirical formula as C7H8.
7.30 C2H6O (6 moles H/1 mole C2H6O)(6.022 X 1023/1 mole H) = 2.64 X 1025 atoms of hydrogen =====================
To determine the number of hydrogen atoms in 8.70 mol of ammonium sulfide (NH4)2S, first find the molar ratio of hydrogen atoms to formula units of ammonium sulfide. There are 8 hydrogen atoms in 1 formula unit of ammonium sulfide. Multiply this ratio by the number of formula units in 8.70 mol of ammonium sulfide to find the total number of hydrogen atoms. This calculation gives you the number of hydrogen atoms in 8.70 mol of ammonium sulfide.
