Since molar mass of hydrogen is 1g , the no. of moles = mass of hydrogen given.
or
No. of moles= Given mass of substance/Molar mass of substance
To find the number of moles in 12g of hydrogen, we first need to determine the molar mass of hydrogen, which is approximately 1g/mol. Then we can divide the given mass (12g) by the molar mass (1g/mol) to find that there are 12 moles of hydrogen in 12g.
To find the number of moles of hydrogen gas, we first need to convert the mass of hydrogen gas from grams to moles using the molar mass of hydrogen gas (2 g/mol). 5.04 grams of hydrogen gas is equal to 5.04 g / 2 g/mol = 2.52 moles of hydrogen gas.
2.5 moles H2O (2 moles H/1 mole H2O) = 5 moles of hydrogen
Well if one mole of water = 2 moles of hydrogen and 1 mole of oxygen, than 2moles of water = 4 moles of hydrogen and 2moles of oxygen.
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 number of moles of hydrogen in 3.5 moles of (NH4)2CO3, first identify the stoichiometry of the compound. In (NH4)2CO3, there are two moles of hydrogen per mole of compound. Therefore, in 3.5 moles of (NH4)2CO3, there would be 2 * 3.5 = 7 moles of hydrogen.
To find the number of moles in 12g of hydrogen, we first need to determine the molar mass of hydrogen, which is approximately 1g/mol. Then we can divide the given mass (12g) by the molar mass (1g/mol) to find that there are 12 moles of hydrogen in 12g.
To find the number of moles of hydrogen gas, we first need to convert the mass of hydrogen gas from grams to moles using the molar mass of hydrogen gas (2 g/mol). 5.04 grams of hydrogen gas is equal to 5.04 g / 2 g/mol = 2.52 moles of hydrogen gas.
2.5 moles H2O (2 moles H/1 mole H2O) = 5 moles of hydrogen
The atomic mass of hydrogen is 1.008 and that for chlorine is 35.45. The moles of hydrogen available are therefore 0.490/1.008 = 0.486 and the moles of chlorine available, 50/35.45, are greater than 1. Each molecule of hydrogen chloride requires one atom each of chlorine and hydrogen. Therefore, with the specified conditions, hydrogen is stoichiometrically limiting, and 0.486 moles of HCl can be made.
N2 + 3H2 -----> 2NH3 so 3 moles of hydrogen produce 2 moles of ammonia. Therefore 12.0 moles of hydrogen will produce 8 moles of ammonia.
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 molar mass of hydrogen peroxide (H2O2) is 34.01 g/mol. To find the mass of 1.50 moles, you would multiply the number of moles by the molar mass: 1.50 moles * 34.01 g/mol = 51.015 grams. So, the mass of 1.50 moles of hydrogen peroxide is 51.015 grams.
You can determine the moles of HCl formed by using a balanced chemical equation for the reaction between hydrogen gas and chlorine. Calculate the stoichiometric ratio of hydrogen to HCl in the balanced equation to determine the moles of HCl formed from the given moles of hydrogen gas.
Well if one mole of water = 2 moles of hydrogen and 1 mole of oxygen, than 2moles of water = 4 moles of hydrogen and 2moles of oxygen.
Methane (CH4) has four atoms of hydrogen per molecule. If there are 3 moles of methane, then there are 12 moles of hydrogen.
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.
