How many moles is 5 grams?
How many moles are 5 grams of calcium ? (Atomic mass of calcium =40u). Thus, there are 0.125 mole in 5 grams of calcium. Thus, 5 grams calcium constitute 0.125 mole of calcium. In the above case, mass of element is 5 grams and molar mass of element is 40g/mol.
How many moles are in NaOH?
Determining the Molar Mass of a Compound

What is a mole in chemistry?
The mole is the amount of substance of a system which contains as many elementary entities as there are atoms in 0.012 kilogram of carbon 12; its symbol is “mol”. … Notice that the definition of the mole is an amount of substance. We will often refer to the number of moles of substance as the amount of the substance.
How many moles is 17.6 g Naoh?
17.6 grams of sodium hydroxide are equal to 0.440 moles of sodium hydroxide.
How many moles of NaOH are in 8.00 g?
The answer is 39.99711.
How many moles of NaOH are present in 27 ml of 0.015 M NaOH?
How many protons are present in 4g of NaOH?
There are about 6.023×10^23 atoms per mol. Therefore, 4 grams of NaOH contains about 6.023×10^22 atoms. 1 atom of NaOH contains 20 protons (11+8+1). Multiply that by the number of atoms in 4 grams to get a total of 1.2046×10^24 protons.
How many atoms are there in 40g of NaOH?
1 mole of NaOH =40g by mass /40g by molar mass. Which is =1. 1 mole of NaOH contains 7.53*10^23 atoms.
