How many moles is 2.3 grams sodium?
Answer & Solution
Molecular mass of Sodium is 23 u. So, 23 g of sodium is equal to 1 mole. The number of mole in 2.3 g = 2.3 / 23 = 0.1 mole.
How many grams are in 2.5 moles of sodium?
And since we know that 1⋅mol of sodium has a mass of 22.99⋅g , we got a mass of 2.50⋅mol×22.99⋅g⋅mol−1=57.5⋅g with respect ot sodium.
How many moles are in a gram of sodium?
If you refer to your periodic table, the molar mass of Na (sodium) is 23.0 g/mol.
How many moles are in sodium?
In grams, a mole is one formula mass. For example, 1 mol of sodium (Na) has a mass of 22.9898 g (the mass on the periodic table). And 1 mol of chlorine (Cl) has a mass of 35.453 g (the mass on the periodic table).
How many moles are there in 5g of sodium?
Moles = mass / molar mass
So, 0.125 moles are present in 5g of NaOH.
How many grams are in 4.5 moles of sodium?
The mass of 4.5 moles of sodium fluoride is 189g.
How many grams are there in 2.5 moles of NaCl?
Answer: molar mass of NaCl is 58.5 gm/mol. This refers to the fact that 1 mole of NaCl weighs 58.5 gram.
How many atoms of sodium are present in 3 moles of sodium and what is the mass of it?
To calculate atoms from moles, multiply given moles by 6.022×10^23 atoms/mol. 3 mol Na × (6.022×10^23 atoms Na/1mol Na) = 1.807×10^24 atoms Na.
What is moles to grams?
In order to convert the moles of a substance to grams, you will need to multiply the mole value of the substance by its molar mass.
