How many sulfur atoms are in a molecule of sulfuric acid (H2SO4)?
We know from looking at the molecular formula that one mole of molecules of H2SO4 contains 2 moles of atoms of hydrogen, 1 mole of atoms of sulfur and 4 moles of atoms of oxygen.
How many moles of C6H6 are there in195g of C6H6?
C6H6 is the molecule of benzene and it's molecular weight is 78, calculated as 6 x 12 +6 x 1=78 and you will understand it if you know some basics of chemistry. then, You know that each mole of a molecule weighs exactly those number of grams as much as is its molecular weight. That means if a molecule has 'M' as its molecular weight, then one mole of it weighs exactly M grams when actually weighed using a weighing machine. This means one mole of benzene weighs 78 grams. then 195 grams of C6H6 has (1/78)x195 moles or 195/78 moles in it.
How many moles are in a molecule?
The amount of moles in a molecule:1 molecule * 1 mole/6.022 x 1023 molecules = 1.66 x 10-24 molesDoes everyone have general chemistry tests this week?yes
How many moles of MgCl2 are there in 313 g of the compound?
Approx 3.29 moles.
How many DNA molecules are in a chromosomes?
There is one double helix DNA molecule per chromosome.
What does stoichiometry use to relate to moles of one molecule of another?
Stoichiometry uses coefficient ratios to relate moles of one molecule to moles of another
What does stoichiometry use to relate moles of one molecule to moles of another?
Stoichiometry uses coefficient ratios to relate moles of one molecule to moles of another
How many hydrogen atoms are in one mole of CuNH4Cl3 molecule?
The answer is 4 moles.
How many moles of bromine will be formed upon the complete reaction of 0.196 moles bromine trifluoride?
The atoms in the reacts are always present in the products. There is one mole of bromine per molecule and .196 moles of the molecule. Thus, there will be .196 mols of bromine present after the reaction.
How many atoms are in 1.38 moles of nitrogen?
1.38 moles of nitrogen equal16,62110876532.1023 atoms; the molecule of nitrogen is diatomic.
How many moles of hydrogen are present in 3 moles of methane?
Methane (CH4) has four atoms of hydrogen per molecule. If there are 3 moles of methane, then there are 12 moles of hydrogen.
How do you cal moles?
One mol is equal to molar mass in grams of a molecule.
How may moles of hydrogen are in H2S?
There are no moles.There are 2 atoms in one molecule.
How many lone pairs of electrons are in a nitrogen molecule?
There are 2 non bonding pairs in a nitrogen molecule
How many Moles of Na react with how many Moles of Cl?
Balanced equation first. NaOH + HCl >> NaCl + H2O Everything is one to one, so 1.222 moles HCl (1mole NaOH/1mole HCl) = 1.222 moles NaOH
How many moles of carbon atoms can be obtained from the decomposition of C6H6 in a 1.68 moles sample?
10.08 moles (there are six carbon atoms per molecule of C6H6, hence, six times the number of moles of carbon can be produced).
How many moles of ammonium ions are in 4.50 mol NH4 2CO3?
There are 9 moles of NH4 (Ammonium ions) in Ammonium carbonate. There are 2 moles of NH4 per molecule and 4.5 molecules, so 2 moles times 4.5 is 9 moles.
