What is the total number of atoms in the compound 4HNO3?
The compound 4HNO3 consists of 4 moles of nitric acid (HNO3). Each molecule of HNO3 contains 5 atoms (1 nitrogen and 3 oxygen atoms). Therefore, the total number of atoms in 4HNO3 is 4 moles * 5 atoms/mole = 20 atoms.
What is the total number of atoms in a sample of cocaine hydrochloride C17H22ClNO4 of mass 24.5 mg?
To find the total number of atoms in a sample of cocaine hydrochloride, you need to calculate the number of moles using the formula: moles = mass (in grams) / molar mass. Then, you multiply the number of moles by Avogadro's number (6.022 x 10^23) to get the total number of atoms.
How many atoms in a mole of aluminum III oxide?
In one mole of aluminum III oxide (Al2O3), there are 2 moles of aluminum atoms (since there are 2 aluminum atoms in each formula unit of Al2O3) and 3 moles of oxygen atoms. Therefore, one mole of aluminum III oxide contains 2 + 3 = 5 moles of atoms. Avogadro's number (6.022 x 10^23) of atoms can be found in one mole of any substance.

How many moles of O atoms are present in a 254g sample of carbon dioxide?
To find the number of moles of oxygen atoms in a 254 g sample of carbon dioxide (CO₂), first calculate the molar mass of CO₂, which is approximately 44 g/mol (12 g/mol for carbon and 32 g/mol for two oxygen atoms). The number of moles of CO₂ in the sample is 254 g ÷ 44 g/mol = about 5.77 moles. Since each molecule of CO₂ contains two oxygen atoms, the total number of moles of oxygen atoms is 5.77 moles × 2 = approximately 11.54 moles of O atoms.
What is the total number of atoms in the compound 4HNO3?
The compound 4HNO3 consists of 4 moles of nitric acid (HNO3). Each molecule of HNO3 contains 5 atoms (1 nitrogen and 3 oxygen atoms). Therefore, the total number of atoms in 4HNO3 is 4 moles * 5 atoms/mole = 20 atoms.
How many moles of electrons are gained when three moles of oxygen atoms are reduced to oxide ions?
When three moles of oxygen atoms (O) are reduced to oxide ions (O²⁻), each oxygen atom gains two electrons. Therefore, for three moles of oxygen atoms, the total number of moles of electrons gained is 3 moles of O × 2 moles of electrons per mole of O, which equals 6 moles of electrons. Thus, 6 moles of electrons are gained in this reduction process.
Three moles of N2O4 contains?
Three moles of N2O4 contains six moles of nitrogen atoms (N) and twelve moles of oxygen atoms (O), since each molecule of N2O4 consists of two nitrogen atoms and four oxygen atoms. Therefore, in total, there are 18 atoms in three moles of N2O4.
How many oxygen atoms in 5 g of sodium dichromate?
Sodium dichromate (Na₂Cr₂O₇) has seven oxygen atoms per formula unit. To determine the number of moles in 5 g of sodium dichromate, we first calculate its molar mass, which is approximately 261.97 g/mol. This means there are about 0.019 moles of sodium dichromate in 5 g. Since each mole contains 7 moles of oxygen atoms, the total number of oxygen atoms is about 0.019 moles × 7 × 6.022 × 10²³ atoms/mole, which equals approximately 7.98 × 10²² oxygen atoms.
How do you calculate how many oxygen atoms are there in 2.50 grams of oxygen gas?
To calculate the number of oxygen atoms in 2.50 grams of oxygen gas (O2), you will first need to convert grams to moles using the molar mass of O2 (32 g/mol). Then, use Avogadro's number (6.022 x 10^23) to determine the number of oxygen molecules in moles. Since there are 2 oxygen atoms in each O2 molecule, you will multiply the number of moles by 2 to find the total number of oxygen atoms.
How many o atoms are present in 50gram of caco3?
There are 2 oxygen atoms in one molecule of CaCO3. To calculate the number of oxygen atoms in 50 grams of CaCO3, you first need to find the number of moles of CaCO3 using its molar mass. Then, multiply the number of moles by the number of atoms of oxygen per molecule of CaCO3 (2) to find the total number of oxygen atoms.
How many oxygen atoms are present in a 14.0 g sample of Cu(NO3)2?
