Will 1 mol of sugar have the same effect as 1 mol of table salt in lowering the freezing point of water?
no because the mol of sugar is 34 g while salt's mol is 5.8 grams
What is the mass of BeC2O4 if 3.21g of BeC2O4-3H2O is heated to 220 degrees Celsius?
BeC2O4 = 97.0 g/1 mol BeC2O4-3H2O = 151.0 g/1 mol 3.21 g BeC2O4-3H2O * 1 mol/151.0 g = 0.021258 mol BeC2O4-3H2O 0.021258 mol BeC2O4-3H2O * 97.0 g/1 mol = 2.06 g BeC2O4
What is the amount of CO2 produced on burning 12g of carbon in air is?
44 grams of CO2 (1 mol CO2 from 1 mol C if enough oxygen, air, is available)
How many moles of N 2 reacted if 0.50 mol of NH 3 is produced?
First make the reaction equation balanced for N-atoms (co-existant in both formula)N2O5 + H2O --> 2 HNO3So 1.02 mole HNO3 is produced from:1.02 x 1 (N per HNO3) / 2 (N per N2O5) = 0.51 mol N2O5
How many moles are in 291.68 grams of hydrochloric acid?
To calculate moles of HCl in 291.68 grams, use the molar mass of HCl which is 1 + 35.5 = 36.5g/mole. 291.68 g x 1 mol/36.5 g = 7.99 moles HCl (3 sig figs)
How do you convert no of moles to no of particles?
(desired moles)(6.02x1023part/1 mol)=answer
How many particles are present in 1 mol of a pure substance?
One mol of a pure substance contains 6.0221367 x 10^23 particles according to Avogadro's number.
Convert mmol to mol?
1 mEq=1 mmol/valence e.g.For sodium, 1 mEq=1mmol/1 (valence of sodium=1) means, 1 mmol sodium=1 mEq of sodium take for calcium,valence=2 1 1 mEq of calcium=1mmol/2=0.5 mmol of calcium
How many particles are in 1 mole of carbon?
Number of particles = number of mol x avogadro constant = 1 x 6.02 x 1023
How many representative particles are in 4.51 g of a molecular compound with a molar mass of 273 grams?
4.51 g x 1 mol x 6.022 x 1023 molecules = 9.95 x 1021 molecules .............273 g ............... 1 mol
How many molecules are in 3.4 moles?
(3.4 mol / 1) * (6.022 x 1023 particles / 1 mol) = 2.04748 x 1024 particles.
How many mol of water will be produced from combining 4.85 mol of oxygen with excess hydrogen?
Exactly the same number of mols. 1 mol of oxigen atoms produces 1 mol of water molecules.
How many mol of H are in 4.51 mol H2O?
In 1 molecule of H2O, there are 2 atoms of H. Therefore, in 1 mol of H2O, there are 2 mol of H. So, in 4.51 mol of H2O, there would be 4.51 * 2 = 9.02 mol of H.
How many atoms are in 1 mole of zinc atoms?
3 moles of Zn is equal to 18.09x1023 atoms. I used Avogadro's Number : 6.03x1023 particles/mol This number is the number of atoms or molecules in a mol of any substance. 3 moles X 6.03x1023 particles/mol = 18.09x1023 atoms
How many mmol are in 3.5 mol?
There are 3500 mmol in 3.5 mol. To convert mol to mmol, you multiply by 1000 since there are 1000 mmol in 1 mol.
How many atoms in 1 mol of chlorine?
There are approximately 6.022 x 10^23 atoms in 1 mol of chlorine, according to Avogadro's number.
How many gram of water is equal to 2.2 mol of water?
2.2 mol water = 2.2 (mol) * 18 (g/mol) water = 39.6 (mol*g/mol) = 40 g18 g/mol = mol mass of H2O = 2*H + 1*O = (2*1 + 16) g/mol
