You calculate it by using Avogadro's number: 6.022 x10 23 which is one mole of substance.
1.00 x 1024 divided by 6.022 x 1023 = 10 divided by 6.022 = 1.661 mol H2O
Use the molar mass of water (18.02 g mol-1) to get to the mass in grams.
18.02 g x 1.661 mol = 29.93 g H2O

What is the mass of 3.2 moles of water?
The molar mass of water (H2O) is approximately 18.015 g/mol. To find the mass of 3.2 moles of water, you multiply the number of moles by the molar mass: 3.2 moles x 18.015 g/mol = 57.648 g. So, the mass of 3.2 moles of water is approximately 57.648 grams.
How do you Convert 40.79 kilojoules per mole to joules per grams?
To convert from kilojoules per mole to joules per gram, you need the molar mass of the substance. Once you have the molar mass, you can convert as follows: 1 kJ/mol = 1000 J/mol 40.79 kJ/mol = 40.79 * 1000 J/mol = 40790 J/mol Then, divide by the molar mass in grams/mol to get joules per gram.
Use the following balance equation to answer this question n2h4 plus 2h2o2 -- n2 plus 4h2o How many grams of h2o are produced from 27 grams of n2h4?
First, calculate the molar mass of N2H4 (hydrazine) to be 32 g/mol. Use the stoichiometry of the balanced equation to find the molar ratio of N2H4 to H2O, which is 1:4. Next, determine the number of moles of N2H4 in 27 grams and then use the molar ratio to find the number of moles of H2O produced. Finally, convert the moles of H2O to grams using the molar mass of H2O (18 g/mol).

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.
What is 1 mol of H2O in grams?
in order to find the mass of H20 you need the molar mass which is 18.01g/mol and to calculate the mass you just multiply by the number of moles. 18.01 * .20 = 3.60g
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).
How many grams of h2o and c3h6 can be formed from 6 grams of c3h8o?
To find the grams of H2O and C3H6 formed from 6g of C3H8O, first calculate the molar mass of C3H8O: 44.1 g/mol. Then, using the stoichiometry of the reaction yielding H2O and C3H6 from C3H8O, you can determine the grams produced. The balanced reaction is C3H8O -> H2O + C3H6, and for every 1 mol of C3H8O, you get 1 mol of H2O and 1 mol of C3H6. So, 6g of C3H8O yields 6g of H2O and 6g of C3H6.
What is the mass of 2.00 mol h2o?

How many moles of water are present in 48 grams?
To find the number of moles in 48 grams of water, we first need to calculate the molar mass of water (H2O), which is approximately 18 grams/mol (1 mol of H2O = 18 grams). Then, we divide the given mass (48 grams) by the molar mass to get the number of moles. In this case, 48 grams / 18 grams/mol ≈ 2.67 moles of water.
How many molecules are there in 200 grams of h2o?

How many molar mass in g mol of dinitrogen pentoxide?
N2O5 Has a molar mass of 108.01 g/mol 1.73 mol x 108.01 g/mol = 187 grams
What is the mass of 5.30 mol H2O?
1 mol of water is the molecular mass turned into grams, so 2x1 for the hydrogen give us 2g and then we add the 16g for the oxygen and we can say that 1 mole of water weighs 18g.Now we do some simple maths. Ratios stuff. If you don't get it post another question...If 1mol = 18g and 5.3mol = xgthen x = (5.3 x 18 )/ 1= 95.4gSo 5.3 mol of water weighs 95.4g
