For this you need the atomic (molecular) mass of NO. Take the number of grams and divide it by the Atomic Mass. Multiply by one mole for units to cancel. NO=30.0 grams
6.64 grams NO / (30.0 grams)= .221 moles NO

To find the number of moles in 6.64 grams of nitrogen monoxide, you need to divide the given mass by the molar mass of nitrogen monoxide (NO), which is 30.0 g/mol.
moles = mass / molar mass moles = 6.64 g / 30.0 g/mol moles = 0.2213 moles
To find the grams of nitrogen dioxide needed, first calculate the moles of nitrogen monoxide using Avogadro's number. Then, use the balanced chemical equation to determine the moles of nitrogen dioxide required. Finally, convert moles to grams using the molar mass of nitrogen dioxide.
To calculate the grams of water formed, we first need to determine the moles of nitrogen and oxygen produced. Using the given data, we find that 14 grams of nitrogen is equivalent to 1 mole and 8 grams of oxygen is also equivalent to 0.5 moles. In the explosion, these moles of nitrogen and oxygen will combine with hydrogen to form water. Since the molar ratio of hydrogen to nitrogen and oxygen is 2:1, the moles of water produced will be 1 mole (from nitrogen) + 0.5 moles (from oxygen) = 1.5 moles. Finally, converting moles to grams, 1.5 moles of water is equal to 18 grams. Thus, 18 grams of water would form during the explosion.
To calculate the number of moles of nitrogen gas in 35.7 g, you can use the molar mass of nitrogen, which is 28 g/mol. First, divide the given mass by the molar mass to find the number of moles: ( \frac{35.7 , \text{g}}{28 , \text{g/mol}} \approx 1.275 , \text{mol}). Therefore, there are approximately 1.275 moles of nitrogen gas in 35.7 g.
To find the number of molecules of carbon monoxide in 3.69 grams, first calculate the number of moles using the molar mass of carbon monoxide (28.01 g/mol). Next, use Avogadro's number to determine the number of molecules in those moles of carbon monoxide.
To find the number of moles, you need to first convert 21.4 mg of nitrogen dioxide to grams by dividing by 1000 (since 1 gram = 1000 mg). Then, calculate the moles using the molar mass of nitrogen dioxide (NO2), which is 46.01 g/mol. 21.4 mg is equal to 0.0214 grams. Dividing 0.0214 g by the molar mass of NO2 gives you approximately 0.00047 moles of nitrogen dioxide.
