How many moles are in 80 grams of NaOH?
= 80 / 40= 2 mol .
How many molecules are present in 80 grams of sodium hydroxide?
In 80 grams there will be 2 molecules of NaOH, so mass of Sodium would be 23 x 2 = 46g.
How many moles are in 1 gram of sodium hydroxide?
The molar mass tells you the mass of exactly one mole of a given substance. In this case, sodium hydroxide has a molar mass of 39.997 g mol−1 , which implies that one mole of sodium hydroxide has a mass of 39.997 g .
How many moles are in 4 grams of NaOH?
How many moles are present in 8g of sodium hydroxide?
The answer is 39.99711.
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.
What is the mole formula?
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).
What is the mass of 0.5 mole of sodium hydroxide?
However, in expressing the concentration as M (molarity) the volume of the solution is also taken into account. Thus, 0.5 mole of NaOH represents simply 20 g of the base while 0.5 M means 20 g of the base or NaOH dissolved per litre of the solution.
How many grams are in 1.5 moles of water?
Conclusion: Thus it can be inferred that the mass of 1.5 moles of water is 27g.
