How many molecules are in .75 g of ammonia?
This is a chemical calculation. there are 0.04166 moles in it.
How many water molecules are in a block of ice containing 1.25 moles of water?
One mole of a substance has 6.022 E23 units. This means that in .75 moles there are 4.52 E23 molecules.
What is the molarity of a solution of sodium hydroxide if it contains 0.5 moles in 75mL of solution?
Molarity means moles per litre. So here you have to divide the moles by 75 and multiply by 1000. 0.5/75*1000, which is 6.667 molar.
What is the number of moles in 24 g of oxygen gas?
Relative Atomic Masses: Fe = 55.84 F = 18.9 You have 3 F so, 18.9 * 3 = 56.7 56.7 + 55.84 = 112.54 This is our formula mass. 24 * (1 mol/112.54) = 0.2127 Mols. - Number of moles in FeF3 * by Avogadro Constant: 0.2127 * 6.02 x10^23 = 1.280 x10^23 molecules :)
How many moles of H are in 0.75 moles of H2SO4?
1.5 moles of Hydrogen. In every mole of H2SO4 (Sulfuric Acid) there are 2 moles of Hydrogen atoms. So, in .75 moles of Sulfuric Acid, there would be 1.5 (double the moles of sulfuric acid) moles of Hydrogen.

This is a chemical calculation. there are 0.04166 moles in it.
If a car produces 88 g of co2 how many grams of o2 are used up in the reaction?
The chemical formula of carbon dioxide is CO2. This shows that each molecule of carbon dioxide contains two oxygen atoms. The formula mass is about* [12 + (2 X 16)] or 44. 75/44 is about 1.7; therefore the specified amount of carbon dioxide is that many moles of the gas. Oxygen normally exists as diatomic molecules, so that the number of molecules of oxygen gas required is the same as the number of moles of carbon dioxide produced. This number is about 1.7 times Avogadro's number, or about 1.02 X 1024. *The approximate atomic mass of carbon is 12 and that of oxygen is 16.
How many moles are in 75 grams of sulfur?
For this you need the atomic mass of He. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel.75.0 grams He / (4.00 grams) = 18.8 moles He
How many atoms are contained in 6.75 moles of C2H6?
6.02 X 1023 particles per mole X .75 moles = 4.52 X 1023 molecules.
How many moles of water ( dihydrogen oxide) are present in 75 grams?
75 grams water is equal to 4,166 moles.
How many water molecules are in a block of ice containing 1.25 moles of water?
One mole of a substance has 6.022 E23 units. This means that in .75 moles there are 4.52 E23 molecules.
How many hydrogen atoms are present in 75.0 of g H2O?
The gram-molecular mass of H2O is 18.01. Therefore, 75.0 grams contains 75.0/18.01 = 4.16 moles. Each molecule contains two hydrogen atoms. Therefore, the number of hydrogen atoms = 2(4.16)(6.022 X 1023) = 5.01 X 1024 atoms.
What is the molarity of a solution of sodium hydroxide if it contains 0.5 moles in 75mL of solution?
Molarity means moles per litre. So here you have to divide the moles by 75 and multiply by 1000. 0.5/75*1000, which is 6.667 molar.

How many grams are in 0.75 moles of SO2?
.75 moles times 64 grams/mols = 48 grams
How many moles of H are in 0.75 moles of H2SO4?
1.5 moles of Hydrogen. In every mole of H2SO4 (Sulfuric Acid) there are 2 moles of Hydrogen atoms. So, in .75 moles of Sulfuric Acid, there would be 1.5 (double the moles of sulfuric acid) moles of Hydrogen.
How many moles are in 75.00 grams of hydrogen?
How many hydrogen atoms are in 35.0 grams of hydrogen gas?
