What mass of zinc metal is required to produce 2.40g of zinc chloride?
To calculate the mass of zinc metal required to produce zinc chloride, you need to find the molar mass of zinc chloride (ZnCl2). The molar mass of ZnCl2 is 136.3 g/mol, which means that for every mole of ZnCl2 produced, you need 1 mole of zinc metal. Since 1 mole of ZnCl2 corresponds to 2 moles of zinc (from the formula ZnCl2), the mass of zinc metal required is 2.40g * (65.38 g Zn/ 136.3 g ZnCl2) = 1.15g.
When 1 gram of zinc chloride ZnCl2 is dissolved in water the heat evolved is 0.53kJ Calculate the molar heat of substance of solution of zinc chloride?
To calculate the molar heat of solution of zinc chloride, we use the heat evolved by dissolving 1 gram of ZnCl2 in water. First, we convert the mass of ZnCl2 to moles using its molar mass of 136.3 g/mol. Then, we divide the heat evolved by the number of moles dissolved to get the molar heat of solution. In this case, the molar heat of solution would be 3.89 kJ/mol.
What is the mass of 0.0435 mol zinc chloride?
To find the mass of zinc chloride (ZnCl2) in 0.0435 mol, you need to calculate the molar mass of ZnCl2, which is 65.38 g/mol. Multiplying 0.0435 mol by the molar mass gives a mass of approximately 2.84 g.
What mass of silver chloride can be produced from 1.59L of a 0.300M solution of silver nitrate?
To find the mass of silver chloride produced, first calculate the moles of silver nitrate using Molarity = moles/volume. Then, use the mole ratio from the balanced chemical equation to find the moles of silver chloride produced. Finally, multiply the moles of silver chloride by its molar mass to find the mass of silver chloride produced.
What is the mass of 6.80 moles of magnesium chloride MgCl2 express the value and units?
The molar mass of magnesium chloride MgCl2 is 95.21 g/mol. To find the mass of 6.80 moles, you would multiply the number of moles by the molar mass: 6.80 moles * 95.21 g/mol = 647.868 g. Therefore, the mass of 6.80 moles of MgCl2 is 647.868 grams.

How many grams of zinc chloride could be formed from the reaction of 4.96g of zinc with excess HCl?
The reaction of zinc with hydrochloric acid is simplified as Zn + 2 HCl = ZnCl2 + H2. This means for every mole of zing, 1 mole of ZnCl2 is formed. 4.96 grams zinc is equal to .0759 moles, so 5.17 grams of zinc chloride would be optimally produced.
What is number of grams in 3 moles of ammonium chloride?
The molar mass of ammonium chloride (NH4Cl) is approximately 53.49 g/mol. To find the mass of 3 moles, multiply the molar mass by the number of moles: 3 moles x 53.49 g/mol = 160.47 grams of ammonium chloride.
How many moles of potassium chloride are there in a 100.0g sample of potassium chloride?
To calculate the number of moles of potassium chloride in a 100.0g sample, you need to divide the mass of the sample by the molar mass of potassium chloride. The molar mass of potassium chloride is approximately 74.55 g/mol. Therefore, 100.0g ÷ 74.55 g/mol = approximately 1.34 moles of potassium chloride in the sample.
How many grams of ZnCl2 are formed from150 g of Zn and 73 g of HCl?
To determine the amount of ZnCl2 formed, we first need to find the limiting reactant. Zn is the limiting reactant in this case. The balanced chemical equation is: Zn + 2HCl -> ZnCl2 + H2. Using the given mass of Zn, calculate the moles of Zn, then use the mole ratio from the balanced equation to find the moles of ZnCl2 formed. Finally, convert the moles of ZnCl2 to grams.
Mass of aluminum chloride?
The molar mass of aluminum chloride (AlCl3) is approximately 133.34 g/mol. To find the mass of aluminum chloride, you would need to know the amount of substance (in moles) and then use the molar mass to calculate the mass. For example, if you had 2 moles of aluminum chloride, the mass would be 2 moles * 133.34 g/mol = 266.68 grams.
