WebAnswer (1 of 4): Moles are usually underground, not under water! Having said that however and assuming that they want to go for a swim it would realy depend on the size of the moles! WebWe start from the ideal gas law, PV = NkT , and multiply and divide the equation by Avogadro’s number NA. This gives P V = N N AN AkT P V = N N A N A k T. Note that n = N NA n = N N A is the number of moles. We define the universal gas constant R = NAk, and obtain the ideal gas law in terms of moles.
Web7 okt. 2024 · I would convert the 1 kg of CaCO3 into grams and then moles. (1kg CaCO3) x (1000g/1kg) x (1mol/100.0869g -- molar mass of CaCO3) = 9.99131 which is about 10 mol CaCO3. Based on the molar ratio in the balanced equation, 1 mole of CaCO3 = 1 mole of CO2. Therefore, 10 moles of CO2 will be produced from 1 kg of CaCO3. Hope this helps!

WebThe overall chemical equation says that 1 mole of glucose reacts with 6 moles of oxygen gas for the reaction to occur. So the glucose to oxygen ratio is 1:6, or basically we need 6 times as many moles of oxygen gas as we do glucose for the reaction to happen. So 0.129 x 6 = 0.833 moles of oxygen. Hope that helps.
