The number of molecules in 1 mole is avogadros number, 6.022 X 1023. So in o.5 mole ter would be 3.011 X 1023
For H2 N2 O2 CI2 F2 I2 We find in the nature as diatomic-molecular form. So we need to multiply by two their molar mass. 1 mol of hydrogen is 1x2= 2 gram; 0.5 mol of H2 is 1 gram.

A sample of water contains 3.6 moles of hydrogen atoms How many molecules of water are present in this sample?
Each water molecule contains two hydrogen atoms. Therefore, the number of water molecules present in the sample can be calculated by dividing the number of hydrogen atoms by 2. In this case, 3.6 moles of hydrogen atoms corresponds to 1.8 moles of water molecules. This is equal to approximately 1.08 x 10^24 water molecules.
How many moles are contained in 25.0 g of C6H12O6?
Avogadro's constant expresses the number of elementary entities per mole of substance and it has the value 6.02 × 1023 . Thus there will be 2.5 times Avogadro's constant molecules of C6H12O present. And as each molecule contains 12 atoms of Hydrogen The number of atoms of Hydrogen present will be 12 times the product of 2.5 times Avogadro's constant. = 1.806 * 1025 atoms of hydrogen.
How many hydrogen atoms present in 2grams cholesterol?
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.

How many GRAMS of hydrogen are present in 2.08 moles of water?
In 1 mole of water (H2O), there are 2 moles of hydrogen (H). This means that in 2.08 moles of water, there are 2.08 x 2 = 4.16 moles of hydrogen. To convert moles to grams, we use the molar mass of hydrogen: 4.16 moles x 1.01 g/mol = 4.22 grams of hydrogen.

What is the number of hydrogen atoms in 90 amu of ethane?
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.
How many moles of hydrogen are in 0.80moles of quinine?
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.
