How many moles of molecules are there in 250g of hydrogen nitrate?
To find the number of moles in 250g of hydrogen nitrate (HNO3), we first need to determine the molar mass of HNO3. The molar mass of HNO3 is 63.01 g/mol. Then, we can calculate the number of moles by dividing the given mass by the molar mass: 250g / 63.01 g/mol = approximately 3.97 moles of HNO3 molecules.
How many total atoms are required to prepare 60g of hno3?
To calculate the total number of atoms in 60g of HNO3, you need to convert the mass of HNO3 to moles using its molar mass. Then, you can use Avogadro's number (6.022 x 10^23 atoms/mol) to find the total number of atoms.
What is the molar mass of sulfur?
The molar mass of sulfur is 32.065. Molar mass is the mass per mole of a substance. In other words, Molar Mass = Mass/Amount of Substance.
The molar mass of C3H8O2 is?
to find molar mass you add the molar mass of the carbons 3(amu)+ molar mass of the hydrogens 8(amu) to find molar mass you add the molar mass of the carbons 3(amu)+ molar mass of the hydrogens 8(amu)
What is the molar mass of lithium oxide Li2O?
Lithium has a molar mass of 6.94 g/mol. Oxygen has a molar mass of 16.00 g/mol. Since Lithium Oxide has 2 Lithium atoms, the molar mass is: (6.94 x 2) + 16.00 = 29.88 g/mol.
How do you find the molar mass of HNO3?
To find the molar mass of HNO3, you would add up the atomic masses of hydrogen (H), nitrogen (N), and three oxygen atoms (O) in one molecule of HNO3. The molar mass of HNO3 is approximately 63.01 grams per mole.
By mass of N in HNO3?
The molar mass of nitric acid (HNO3) is approximately 63 g/mol. Nitric acid contains one nitrogen atom, which has a molar mass of about 14 g/mol. This means that the percentage by mass of nitrogen in nitric acid is approximately 22%.

How many moles of HNO3 are present in 450 g of HNO3?
To determine the number of moles of HNO3 present in 450 g, we first need to calculate the molar mass of HNO3, which is approximately 63.01 g/mol. Next, we use the formula moles = mass/molar mass to find the number of moles. Therefore, 450 g of HNO3 is equal to 7.14 moles of HNO3.
How many total atoms are required to prepare 60g of hno3?
To calculate the total number of atoms in 60g of HNO3, you need to convert the mass of HNO3 to moles using its molar mass. Then, you can use Avogadro's number (6.022 x 10^23 atoms/mol) to find the total number of atoms.
How many atoms of zinc react with 1.49 g HNO3?
To find out how many atoms of zinc react with 1.49 g of HNO3, you would first need to balance the chemical equation for the reaction. Then, you can convert the mass of HNO3 to moles using its molar mass. Finally, use the coefficients in the balanced equation to determine the mole ratio between zinc and HNO3 to find the number of atoms of zinc involved in the reaction.
How many grams are in 1 mole of nitric acid?
The molar mass of nitric acid (HNO3) is approximately 63 grams per mole.
How many grams of HNO3 are in 2.6 mols of the compound?
[H=1,N=14,O=16] Gram molar weigt of HNO3=1+14+3x6 =15+48 =63g 1 mole ----------> 63 g 2.6 mole --------> 63x2.6 =163.8 g thus, 163.8g of HNO3 is present in 2.6 moles of compound
What is the molarity of a solution of HNO3 which contains 12.6grams of solute in 500 mL of soulution?
The first step is to calculate the number of moles of HNO3. The molar mass of HNO3 is 63 g/mol. Therefore, 12.6 g is equal to 0.2 moles. Next, you convert the volume of the solution from mL to L (500 mL = 0.5 L). Lastly, divide the number of moles by the volume in liters to get the molarity, which is 0.4 M.
What is the molar mass of SiC?
Molar Mass of Carbon + Molar Mass of Silicon = Molar Mass of SiC. 12.0107 + 28.0855 = 40.0962 g / mol.
A sample of the compound prepared in this experiment weighing 0.1021 g is dissolved in HNO?
To calculate the concentration of the sample, you need to know the volume of HNO3 used to dissolve it. Once you have that information, you can use the formula: concentration (mol/L) = mass of sample (g) / molar mass of compound (g/mol) / volume of HNO3 (L).
What is the molar mass of sulfur?
The molar mass of sulfur is 32.065. Molar mass is the mass per mole of a substance. In other words, Molar Mass = Mass/Amount of Substance.
