How many moles are in 20 grams of water?
so mole of water weighs 18g. which implies 18g of water =1mole. if 18g,=1mole then 20g =20/18. therefore 20g=1.11111.
How do you convert 20 grams of water to moles?
so 20 g of water = 1.11 mol of water. Q3. Convert into mole.
What is mass of 20g of water?
= 18 g.
How many moles are in 16g of water?
16g of water is equal to 8/9 or 0.88.. moles.
How many moles are in water?
The number of atoms is an exact number, the number of mole is an exact number; they do not affect the number of significant figures. The average mass of one mole of H2O is 18.02 grams. This is stated: the molar mass of water is 18.02 g/mol. Notice that the molar mass and the formula mass are numerically the same.
How many moles are there in 9 g of water?
Water has 18 grams per mole so 9 grams is 0.5 moles of water.
How do you convert to moles?
A substance’s molar mass is calculated by multiplying its relative atomic mass by the molar mass constant (1 g/mol). The molar mass constant can be used to convert mass to moles. By multiplying a given mass by the molar mass, the amount of moles of the substance can be calculated.
How many grams is 2 moles of water?
It is equal to Avogadro’s number (NA), namely 6.022 x1023. If we have one mole of water, then we know that it will have a mass of 2 grams (for 2 moles of H atoms) + 16 grams (for one mole O atom) = 18 grams.
How many grams is 5 moles of water?
Answer: Since one mole of water is made of two moles of Hydrogen (1.01 g/mol) and one mole of Oxygen (15.99 g/mol) its mass would be 18.01 g. Five moles of water whould have a mass of 90.05 g.
How do you find moles of water?
As in the given question we have to calculate how many moles are present in the 25 grams of water and for this we have to divide the given weight of water by the molecular weight / mass of water. Hence, 1.38 moles (mol) are present in 25 grams of water.
