Answer:
The molar mass of a substance is defined as the mass in grams of 1 mole of that substance. One mole of isotopically pure carbon-12 has a mass of 12 g. ... That is, the molar mass of a substance is the mass (in grams per mole) of 6.022 × 1023 atoms, molecules, or formula units of that substance.
Explanation:
The amount of heat required that is used to change 1l of water into vapour at atmospheric pressure is known as latent heat of vaporisation
Answer:
3.56L will be the obtained volume
Explanation:
0.3 M → Molarity
These are the moles of solute (for this case, the solute is KOH) that are contianed in 1L of solution
We dissolved 60 g of solute, so let's determine the moles:
60 g . 1 mol/ 56.1 g = 1.07 moles
Molarity(mol/L) = Mol / Volume(L)
Let's replace data: 0.3M = 1.07 mol / Volume(L)
0.3 mol/L = 1.07 mol / volume
Volume = 1.07 mol / 0.3mol/L = 3.56 L
<span>Looking at the equation, 2 moles of FeO are produced from every 2 moles of CuFeS2. That means 8 moles of CuFeS2 will produce 8 moles of FeO (assuming there is sufficient oxygen, O2, in the reaction)</span>
