To find the number of atoms of nitrogen in 20g of NH4NO3, first calculate the molar mass of NH4NO3 (80.043 g/mol). Next, divide the mass of NH4NO3 by its molar mass to find the number of moles (0.2496 mol). Finally, multiply the number of moles by Avogadro's number (6.022 x 10^23) to determine the number of atoms of nitrogen (1.50 x 10^23 atoms).

How many moles of B in 20g of borax?
To calculate the number of moles in 20g of borax (Na2B4O7), we first need to find the molar mass of borax. By adding the atomic masses of all the elements in borax, we get a molar mass of approximately 201.22 g/mol. Then, we use the formula: moles = mass / molar mass. Substituting in the values, we find that there are approximately 0.10 moles of borax in 20g. Since there are four boron atoms in one molecule of borax, the number of moles of B (boron) would be 0.10 moles * 4 = 0.40 moles.
How many moles in 20g of sodium hydroxide?
To determine the number of moles in 20g of sodium hydroxide, you need to divide the given mass by the molar mass of sodium hydroxide. The molar mass of NaOH is 40 g/mol (sodium: 23 g/mol, oxygen: 16 g/mol, hydrogen: 1 g/mol). So, 20g NaOH / 40 g/mol = 0.5 moles of sodium hydroxide.
What is the density of a mineral sample with a mass of 20g and a volume of 12cm3?
The density of the mineral sample is 1.67 g/cm3. This is calculated by dividing the mass (20g) by the volume (12cm3).
What is alkaline nasal wash?
An alkaline nasal wash is a solution that has a higher pH level, typically created by adding baking soda to water, used to rinse out the nasal passages. This type of nasal wash is believed to help soothe irritated nasal linings and clear out mucus. It is often used as a natural remedy for conditions like allergies, sinusitis, and congestion.
How many moles of so3 are in 20g of so3?
To find the number of moles, you first need to calculate the molar mass of SO3, which is 80.06 g/mol. Then, you can use the formula: moles = mass / molar mass. Thus, for 20g of SO3, you would have 20g / 80.06 g/mol = 0.25 moles of SO3.
