What mass of H2O can be made from 24gO oxygen and 16g H2?
The molar mass of O is 16 g/mol and H is 1 g/mol. From the given masses, we calculate moles: 24 g O / 16 g/mol = 1.5 mol O and 16 g H2 / (2 g/mol) = 8 mol H2. The balanced chemical equation for the formation of water from hydrogen and oxygen is 2H2 + O2 -> 2H2O, so we need twice as many moles of H2 as O2. Hence, 1.5 mol O2 would require 3 mol H2, which is 3/2 * (2 g H2O/mol) = 3 g H2O.
What has the largest mass 5.0mol H20 or 3.5 mol NH3?
Well let's see: H = 1g O = 16g N = 14g H2O = 18g per mole (1 + 1 + 16) NH3 = 17g per mole (14 + 1 + 1) 18 x 5 = 90 17 x 3.5 = 59.5 90>59.5 .: 5.0 mol H2O has a greater mass than 3.5 mol of NH3

The molar mass of H2O =(2 atoms H x 1.00794g/mol H) + (1 atom O x 15.9994g/mol O) = 18.0152g/mol H2O1 mole of H2O = 18.0152g H2O1 mole of H2O molecules = 6.022 x 1023 molecules H2OConvert molecules to moles.5.00 x 102g H2O molecules x (1mole H2O/6.022 x 1023 molecules H2O) =8.31 x 10-22 mole H2OConvert moles to grams.8.31 x 10-22 mole H2O x (18.0152g H2O/1mole H2O) = 1.50 x 10-20g H2OAnswer: The mass in grams of 5.00 x 102g H2O molecules = 1.50 x 10-20g H2O
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.
How many hydrogen atoms are in 360 grams of water?
There are 4.8 x 10^24 hydrogen atoms in 360 grams of water. This is calculated by using Avogadro's number to convert the mass of water to moles, and then using the chemical formula of water (H2O) to determine the number of hydrogen atoms present in 1 mole of water.
Calculate the number of moles of H atoms in 11.5mol H2O?
11.5 mole H2O (2 mole H/1 mole H2O)(6.022 X 10^23/1 mole H)(1 mole H/6.022 X 10^23) = 23.0 moles of H atoms

Is hydrogen another name for water?
No. Hydrogen is H (14 g/mol) and Water is H2O (14x2+16 so 44 g/mol).
What is the percent composition of hydrogen in water?
The formula for water is H2O: Molar mass = 18.02 g / mol H2OIn one mole of H2O there are 2 mol H and 1 mol O:2 mol H1.010 g H = 2.020 g H1 mol H1 mol O16.00 g O = 16.00 g O1 mol OThe percentage of each element is calculated from the quantities in 1 mole as:% element = g element 100g H2O% H...=...2.020 g H... 100......=...11.21 % H18.02g H2O% O...=...16.00 g O... 100......=...88.79 % O18.02g H2ONote: 11.21 + 88.79 = 100.00
What is the formula mass of h20?
The formula mass of H2O (water) is calculated by adding the atomic masses of the elements present in the compound. The atomic masses of hydrogen (H) and oxygen (O) are approximately 1 and 16, respectively. Therefore, the formula mass of H2O is 1 (atomic mass of H) * 2 (number of hydrogen atoms) + 16 (atomic mass of O) = 18.
How many molecules of H2O are there 1.0 grams of H2O?
To find the number of molecules in 1.0 gram of H₂O, we first calculate the number of moles using the molar mass of water, which is approximately 18.02 g/mol. Dividing 1.0 g by 18.02 g/mol gives about 0.0555 moles of H₂O. Using Avogadro's number (approximately (6.022 \times 10^{23}) molecules/mol), we find that there are roughly (3.34 \times 10^{22}) molecules of H₂O in 1.0 gram.
How many gram of water is equal to 2.2 mol of water?
2.2 mol water = 2.2 (mol) * 18 (g/mol) water = 39.6 (mol*g/mol) = 40 g18 g/mol = mol mass of H2O = 2*H + 1*O = (2*1 + 16) g/mol
How many molecules are in 3.5grams of H2O?
There are 23 atoms in 6.0 g of water. Using this formula (6 g H2O)(1 mol H2O / 18 g H2O) = 1/3 mol H2O (1/3 mol H2O)(2 mol H / 1 mol H2O)(6.022 x 10^23 atoms H / 1 mol H) = 4.0 x 10 therefore 23 atoms.
What mass of H2O can be made from 24gO oxygen and 16g H2?
The molar mass of O is 16 g/mol and H is 1 g/mol. From the given masses, we calculate moles: 24 g O / 16 g/mol = 1.5 mol O and 16 g H2 / (2 g/mol) = 8 mol H2. The balanced chemical equation for the formation of water from hydrogen and oxygen is 2H2 + O2 -> 2H2O, so we need twice as many moles of H2 as O2. Hence, 1.5 mol O2 would require 3 mol H2, which is 3/2 * (2 g H2O/mol) = 3 g H2O.
What contributes to the acidity of water?
Protons (H+ ions) from water protolysis 1.0*10-7 mol/L: It is a very very small part of the 55.6 mol water in that litre but it's why pH of water is 7.0!H2O --> H+ + OH-
What has the largest mass 5.0mol H20 or 3.5 mol NH3?
