2.2 mol water = 2.2 (mol) * 18 (g/mol) water = 39.6 (mol*g/mol) = 40 g
18 g/mol = mol mass of H2O = 2*H + 1*O = (2*1 + 16) g/mol

How much joules are gained by water during evaporation?
It takes 333.51 or 334 joules to evaporate 1 gram of H2O.
How to convert 1.5 mol of water into grams?
To convert 1.5 mol of water into grams, you can use the molar mass of water, which is approximately 18.015 g/mol. Multiply 1.5 mol by the molar mass to get the grams of water. Therefore, 1.5 mol of water is equal to 27.02 grams.
How many grams are in 6.3 moles of BH3?
6.3(mol) * 13.83 (g·mol−1)= 87.1 gram BH3
How many moles are there in 237 g of niobium?
Niobium has a atomic weight Ar = 92.9 g mol-1237 g / 92.9 g mol-1 = 2.55 mol
What is the gfm of anhydrous salt?
Based on the category, this answer will refer to sodium chloride, NaCl. Gfm is gram formula mass and is the same thing as molar mass. To find the gram formula mass of NaCl, you add the gram atomic masses (gam) from the periodic table (atomic weights) of the sodium and chlorine atoms in one formula unit. gam Na = 22.99g/mol gam Cl = 35.45g/mol Ggm of NaCl = 22.99g/mol + 35.45g/mol = 58.44g/mol
How much would the freezing point of water decrease if 4 mol of sugar were added to 1g of water?
Adding 4 mol sugar to 1 g (gram) water is impossible !
How much joules are gained by water during evaporation?
It takes 333.51 or 334 joules to evaporate 1 gram of H2O.
How many liters of hydrogen are produced when 117 grams of potassium react with water?
117(g K) * [1.008(g/mol H) / 39.098(g/mol K)] = 3.02 gram hydrogen
In which compound is the percent composition by mass of chlorine equal to 42 percent?
The compound with 42% chlorine by mass is titanium tetrachloride (TiCl4). It has 42% chlorine because the molar mass of chlorine is 35.5 g/mol and the molar mass of TiCl4 is 189.68 g/mol, giving a chlorine mass percentage of 42%.
How many grams of CO2 will be produced by burning 34.3 gram of C3H8?
[ 34.3(gC3H8) / 44(g/mol C3H8)] * [ 3mol CO2 / 1molC3H8 ] * 44(g/mol CO2) = 103 gram CO2
How do you prepare 0.01 M from 65 percent HNO3?
To prepare 0.01 M HNO3 from 65% HNO3: Calculate the required volume of 65% HNO3 needed to make the solution. Dilute the calculated volume of 65% HNO3 with water to achieve the desired 0.01 M concentration. Mix thoroughly to ensure homogeneity.
How many moles are in 3.581023?
3,5810e23 is equal to 0,59 mol.
How many mol of water will be produced from combining 4.85 mol of oxygen with excess hydrogen?
Exactly the same number of mols. 1 mol of oxigen atoms produces 1 mol of water molecules.
Which term is used to represent the mass of 1 mole of molecules of a substance?
This is equal to the molar mass of this substance.
How many grams are in 6.3 moles of BH3?
6.3(mol) * 13.83 (g·mol−1)= 87.1 gram BH3
What is the heat of vaporation of water?
Vaporization heat of water: 40.65 kJ/mol or 2257 kJ/kg or 539.423 calories per gram (very outdated units!)
How many gram are in 238 moles of arsenic?
Atomic mass of Arsenic = 74.9g/mol Using the formula: mass = Atomic mass x number of moles mass = 74.9g/mol x 238 mol = 17826.2 grams
