How many atoms are in 2.5 moles of NaOH?
2.5⋅6.02⋅1023≈1.5⋅1024 sodium atoms.
How many grams is 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 grams of NaOH are in 3 moles of NaOH?
A 3.0 M solution of NaOH has 3.0 moles of NaOH per liter of solution. There are 0.25 L of solution (250mL⋅1L1000mL) , so there are 0.25L⋅3.0mol/L=0.75mol of NaOH. The molar mass of NaOH is 40.0 g/mol, so there are 0.75mol⋅40.0g/mol=30g of NaOH, 30.
How many atoms are in 2 moles of sodium?
If we have 2 mol of Na atoms, we have 2 × (6.022 × 10 23) Na atoms, or 1.2044 × 10 24 Na atoms.
What is the formula for 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.
How many grams are there in 10 moles of sodium?
One mole of any substance is equal to the value of Avagadro number (6.023 x 1023). It can be used to measure the products obtained from the chemical reaction. The unit is denoted by mol. ∴ The mass of 10 moles of sodium sulphite = 1260 grams.
How many moles are in 4 grams of NaOH?
What is the formula for moles?
Avogadro’s number is a very important relationship to remember: 1 mole = 6.022×1023 6.022 × 10 23 atoms, molecules, protons, etc. To convert from moles to atoms, multiply the molar amount by Avogadro’s number. To convert from atoms to moles, divide the atom amount by Avogadro’s number (or multiply by its reciprocal).
How many moles is 5.69 g NaOH?
To change grams of a compound to moles of a compound. For example How many moles is 5.69 g of NaOH? 6.02 x 1023 molec.
How many moles are in 80g of NaOH?
= 80 / 40= 2 mol .
