To find the number of moles of zinc, you can use the formula: moles = mass (g) / molar mass (g/mol). The molar mass of zinc is approximately 65.38 g/mol. Thus, for 125 g of zinc, the calculation would be 125 g / 65.38 g/mol, which equals approximately 1.91 moles of zinc.
0,356 moles of zinc contain 23,27 g.
The answer is 2,7 moles.
To calculate the number of moles of zinc, use the formula: moles = mass (grams) / molar mass (grams/mol). The molar mass of zinc (Zn) is approximately 65.38 g/mol. Therefore, 125 grams of zinc is equal to 125 g / 65.38 g/mol, which is about 1.91 moles of zinc.
To determine the number of moles in 1 g of zinc nitrate, you need to know the molar mass of zinc nitrate. Zinc nitrate has a molar mass of 189.36 g/mol. By dividing 1 g by the molar mass, you can calculate that there are approximately 0.0053 moles of zinc nitrate in 1 g.
There are approximately 8.45 tablespoons in 125g.
The equivalent of 125 g zinc is 1, 91 moles.
0,356 moles of zinc contain 23,27 g.
To find the number of moles of zinc in 15 grams, divide the given mass by the molar mass of zinc. The molar mass of zinc is approximately 65.38 g/mol. Therefore, 15 grams of zinc is equal to 0.23 moles of zinc.
The answer is 2,7 moles.
To calculate the number of moles of zinc, use the formula: moles = mass (grams) / molar mass (grams/mol). The molar mass of zinc (Zn) is approximately 65.38 g/mol. Therefore, 125 grams of zinc is equal to 125 g / 65.38 g/mol, which is about 1.91 moles of zinc.
If the reaction is stoichiometric, 1.30 moles of zinc will generate an equal number of moles of silver. This is based on the balanced chemical equation for the reaction between zinc and silver nitrate.
The formula given shows that each formula unit of KCl contains one atom of potassium. Therefore, the number of moles of potassium will be the same as the number of moles of KCl, and its gram formula mass is 74.55. therefore, the number of moles is 125/74.55 or 1.68, to the justified number of significant digits.
125g = 0.125kg
To determine the number of moles in 1 g of zinc nitrate, you need to know the molar mass of zinc nitrate. Zinc nitrate has a molar mass of 189.36 g/mol. By dividing 1 g by the molar mass, you can calculate that there are approximately 0.0053 moles of zinc nitrate in 1 g.
1 mol of zinc reacts with 2 moles of chlorine to form zinc chloride. Calculate the number of moles of zinc in 5.00g, then use the mole ratio to determine the moles of chlorine needed. Finally, convert the moles of chlorine to grams.
There are approximately 8.45 tablespoons in 125g.
To find the number of moles of zinc, divide the sample's weight by the atomic weight of zinc (65.38 g/mol). This gives approximately 0.534 moles of zinc. To find the number of atoms, multiply the number of moles by Avogadro's number (6.022 x 10^23 atoms/mol) to get around 3.21 x 10^23 atoms in the sample.
