Does one mole of NH3 weigh more than one mole of H2O?
The mass of NH3 mole = its molecular weight = 14 + 3 x 1 = 17 The mass of H2O mole = its molecular weight = 2 x 1 + 16 = 18 This means that one mole of NH3 weigh less than one mole of H2O
What is the mass in grams of 4.5 moles of h2o?
0.25 mole of H2O
How many grams are in one mole of H2O?
one mole of any element is equals to its gam(Gram Atomic Mass) and one mole of any molecule is also equals to that molecules gram atomic mass. Lets calculate the gram molecular mass of water : h2o = 2 hydrogen atoms, 1 oxygen atom = 2 hydrogen x 1g (gram atomic mass of hydrogen) + 1 oxygen x 16g (gram atomic mass of oxygen) = 2 + 16 = 18g Therefore 1 mole of water contains 18grams.
How many grams of H2O do you need to weigh out to have 1 mole of H2O?
To have 1 mole of H2O, you would need to weigh out approximately 18 grams of water (H2O). This is because 1 mole of water molecules (H2O) has a molar mass of about 18 grams/mol (2 grams/mol for hydrogen x 2 atoms + 16 grams/mol for oxygen).
What is the mass of 2 moles of water (H2O)?
A mole of HNO3 weighs 63g (1 + 14 +16x3). Therefore, two moles weigh, 2 x 63 =126 g
How many moles are in 35.1 grams of water?
To teach you how to do this problem: 1. Look at the Periodic Table. O =16 grams/mole, H =1.01 grams/mole 2. Calculate the Molecular Weight of Water. 1*O + 2*H: 16+2.02=18.02g/mole 3. Divide the mass of what you have by the Molecular Weight: 35.1g H2O/(18.02 g H2O/mole H2O) 4. The units g H2O cancel leaving you with mole H2O. 5. 35.1 grams H2O= 1.95 moles H2O
What is the mass in grams of 5.00 x 10 to the 2nd power water molecules?
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
What mass of h2o is produced when 0.400 moles of koh react completely in the following equation koh plus hcl equals kcl plus h2o?
I assume KOH is limiting. Balanced equation. KOH + HCl -> KCl + H2O 0.400 moles KOH (1 mole H2O/1 mole KOH)(18.016 grams/1 mole H2O) = 7.21 grams water produced =====================
How many moles of H2O are there in 1.0 g of H2O?
There are 0.0556 moles of H2O in 1.0 g of H2O. This calculation is obtained by dividing the given mass (1.0 g) by the molar mass of water (18.015 g/mol).
How many mole h2o have in this reaction caco3 plus 2hcl---cacl2 co2 h2o?
Molar ratio's in this balanced equation: 1 + 2 --> 1 + 1 + 1 (H2O) respectively
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
What is the mass or volume of one mole of water?
The molar mass of water (H2O) is approximately 18.015 grams per mole. The volume of one mole of water at standard temperature and pressure (STP) is about 18.0 milliliters.
