How many moles of KF would need to be added to 2500 ml of water to make 1.2 M solution?
1 answer:
The number of moles of KF needed to prepare the solution is 3 moles
<h3>What is molarity?</h3>
Molarity is defined as the mole of solute per unit litre of solution. Mathematically, it can be expressed as:
Molarity = mole / Volume
<h3>How to determine the mole of KF </h3>
Volume = 2500 mL = 2500 / 1000 = 2.5 L Molarity = 1.2 M Mole of KF =?
Molarity = mole / Volume
1.2 = mole of KF / 2.5
Cross multiply
Mole of KF = 1.2 × 2.5
Mole of KF = 3 moles

Answer:
399
Explanation:
Pb(SO4)2 contains 1 atom of Pb, 2 atoms of S and 8 atoms of O. So, atomic mass of Pb(SO4)2 is 207 + 64 + 128 = 399 u. Therefore, molar mass of Pb(SO4)2 is 399 g/mol.HOPE THIS helps. Good Luck
B is the answer I think better sure
Answer:CH3COOH + NaHCO3 > H2O + CO2(g) + CH3COONa
Explanation:acid and base neutralize creating water and CO2 gas along with a salt
Displacement, usually the method that is used to measure the volume of an irregularly shaped object.
An electron because that is the only part able to be lost or gained without nuclear action needed
