How many moles are in 63.0 g of (NH4)2Cr2O7?
To find the number of moles in 63.0 g of (NH4)2Cr2O7, first calculate its molar mass. The molar mass of (NH4)2Cr2O7 is approximately 252.13 g/mol. Using the formula: moles = mass (g) / molar mass (g/mol), we find that the number of moles is 63.0 g / 252.13 g/mol ≈ 0.249 moles.
How many moles are in 14g of silicon?
To find the number of moles in 14 grams of silicon, you can use the formula: moles = mass (g) / molar mass (g/mol). The molar mass of silicon is approximately 28.09 g/mol. Therefore, the number of moles in 14 grams of silicon is 14 g / 28.09 g/mol, which is approximately 0.497 moles.

How many moles are in 4.5 g of AgNO3?
To find the number of moles in 4.5 g of AgNO3, you first need to determine the molar mass of AgNO3 which is 169.87 g/mol. Then you can use the formula: moles = mass / molar mass. Therefore, moles = 4.5 g / 169.87 g/mol ≈ 0.0265 moles.
What is the number of moles in 432 g Mg (OH)2?
The number of moles in 432 g Mg (OH)2 is 7,407.
Find the number of moles in 607 g krypton?
7.24 moles.
What number of moles are present in 10.0 g aspartame?
To find the number of moles in 10.0 g of aspartame, we first need its molar mass. Aspartame has a molar mass of approximately 294.3 g/mol. Using the formula: moles = mass (g) / molar mass (g/mol), we calculate: moles = 10.0 g / 294.3 g/mol, which is approximately 0.034 moles of aspartame.
