How many moles in 60 grams of H2O?
There are approximately 3.33 moles of H2O in 60 grams.
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 moles of water are there in 100 grams of water?
First you find the Molar Mass of water using the values on the periodic table.2 Hydrogen + 1 Oxygen2*1.01 + 16.00 = 18.02 g/molThen using factor-label to cancel out units(100g H2O)*(1 mol H2O / 18.02 g H2O) = 5.54938957 molSo the number of moles in 100g of H2O is about 5.55 moles.Hope that helps.
How many moles of hydrogen atoms are present in 25 grams of water?
For this you need the atomic (molecular) mass of H2O. Take the number of moles and multiply it by the atomic mass. Divide by one mole for units to cancel. H2O= 18.0 grams2.5 moles H2O × (18.0 grams) = 45.0 grams H2O
How many molecules are in 4.21 grams of water?
45 grams H20 x (1 mole H20/18 grams H2O) x (6.02E23 molecules H20/1 mole H2O) the grams H2O and moles H2O cancel out. When you punch it into your calculator, the answer comes out to: =1.505E24 molecules H2O
How many moles of H2O is 7.038 grams of H2O?
The answer is 0,44 moles.
How many moles in 60 grams of H2O?
There are approximately 3.33 moles of H2O in 60 grams.
How many moles are in 53 grams of H2O?
53 grams ÷ 18.01 grams/mole = 2.94 moles
Find the mass in grams of 1.54 moles of H2O?
To find the mass of 1.54 moles of H2O, you can use the molar mass of water. The molar mass of H2O is 18.015 grams/mol. Therefore, the mass of 1.54 moles of H2O would be 1.54 moles * 18.015 grams/mol = approximately 27.75 grams.
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 moles of water H2O are produced from the reaction of 16 grams methane CH4 with an unlimited supply of oxygen O2. How many grams of H2O is this?
Two moles of water are produced.
How many moles of water are in 0.34g of water?
To find the number of moles in 0.34g of water, you first need to calculate the molar mass of water, which is approximately 18g/mol. Then, divide the given mass by the molar mass to get the number of moles. Therefore, 0.34g / 18g/mol ≈ 0.019 moles of water.
How many moles are in 40.0g of h20?
Since moles = mass/molar mass then the number of moles is 40.0/(1+1+16) = 2.22mol to 3sf
How many grams are there in 1.57 moles of water?
1 mole H2O = 18.015g H2O 1.57mol H2O x 18.015g H2O/1mol H2O = 28.3g H2O
How do you convert grams to molecular mass?
To convert grams to molecular mass, you need to divide the given mass in grams by the molar mass of the substance. The molar mass is calculated by adding up the atomic masses of each element in the compound as per the chemical formula. This calculation helps in determining the number of moles present in the given mass of the substance.
How many moles are present in 500.00 g of H2O?
For this you need the atomic (molecular) mass of H2O. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel. H2O= 18.0 grams500.0 grams H2O / (18.0 grams) = 27.8 moles H2O
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
