WebThat is, 1 kilogram of mass is equal to 8.98·10¹⁶ joules of energy or (1 J)/c² = 1.112 650 056 × 10⁻¹⁷ kg. Example: The reaction of 1 kg of antimatter with 1 kg of matter would produce about 1.8×10¹⁷ J, or 180 petajoules of energy, or about 43 megatons of TNT. WebAngelica Chen. Right, one mole of KCl is 6.022•10^23 molecuoes of KCl. When you split it apart, you get 6.022•10^23 atoms of potassium, and the same amount of chlorine atoms. … ceylon woodbine ga
Moles and masses - Higher - Calculations in chemistry (Higher)
Webm = 6 l × 998 kg/m³ = 0.006 m³ × 998 kg/m³= 5.988 kg. It's easier to work with grams, so convert the mass: 5.988 kg = 5988 g. As you already know how the grams to moles conversion work, find the number of moles: n = 5988 g / 18.015 g/mol = 332.4 mol.
