What volume of a 0.550 M solution of potassium hydroxide can be made with 10.7g of potassium hydroxide?
To calculate the volume, first find the number of moles of potassium hydroxide using its molar mass. Then use the molarity to calculate the volume. Calculate moles of KOH: 10.7g / 56.11g/mol = 0.191 moles KOH Volume = moles / Molarity = 0.191 moles / 0.550 mol/L = 0.348 L = 348 mL
How many moles of KF are contained in 347 g of water in a 0.175m KF solution?
This value is 0,06 moles.
How many moles of KF are contained in 347 g of water in a 0.175 m KF solution?
The definition of 0.175 m KF is that 1 kg of water contains 0.175 moles of KF. Thus, 347 g of water is equivalent to 0.347 kg, and to find moles of KF, you calculate as follows:0.175 moles/Kg x 0.347 kg = 0.0607 moles of KF are present (3 significant figures).

How many molecules are present in 347g of CaCl 2?
To find the number of molecules in 347 grams of CaCl₂, first calculate the molar mass of CaCl₂, which is approximately 110.98 g/mol (40.08 g/mol for Ca and 35.45 g/mol for each Cl atom). Then, divide the mass by the molar mass: 347 g ÷ 110.98 g/mol ≈ 3.13 moles. Finally, multiply the number of moles by Avogadro's number (approximately 6.022 x 10²³ molecules/mol): 3.13 moles × 6.022 x 10²³ molecules/mol ≈ 1.89 x 10²⁴ molecules.
How many grams go into 3470 milligrams?

What is the total amount of heat required to melt 347 grams of ice at its melting point?
To calculate the total amount of heat required to melt 347 grams of ice at its melting point, use the formula ( Q = m \times L_f ), where ( m ) is the mass of the ice and ( L_f ) is the latent heat of fusion for ice (approximately 334 J/g). Thus, ( Q = 347 , \text{g} \times 334 , \text{J/g} ), which equals about 116,558 Joules. Therefore, approximately 116.6 kJ of heat is required to melt 347 grams of ice.
How many total ions are present in 347g of CaCl2?
To find the total ions in 347 g of CaCl₂, first calculate the number of moles of CaCl₂ using its molar mass, which is approximately 110.98 g/mol. Dividing 347 g by the molar mass gives about 3.13 moles of CaCl₂. Each formula unit of CaCl₂ dissociates into one calcium ion (Ca²⁺) and two chloride ions (Cl⁻), totaling three ions per formula unit. Therefore, the total number of ions is 3.13 moles × 3 ions/mole = approximately 9.39 moles of ions, or about 5.65 × 10²⁴ ions.
