∙ 10y agoTo find the number of moles in fifteen kg of butane, first calculate the molar mass of butane (C4H10) which is 58.12 g/mol. Then convert fifteen kg to grams (15000 g). Finally, divide the mass in grams by the molar mass to find the number of moles, which in this case is approximately 258.27 moles.
When 1.35 kg of butane is burned, approximately 49,290 kJ of heat energy is released.
The molality of a solution is calculated by dividing the moles of solute by the mass of the solvent in kilograms. In this case, the molality would be 2 moles / 6 kg = 0.33 mol/kg.

First, calculate the moles of cane sugar: 38.0 g / 342.3 g/mol = 0.111 moles. Then, calculate the molality using the formula: molality = moles of solute / kg of solvent. Since 175 g of water is equivalent to 0.175 kg, molality = 0.111 moles / 0.175 kg = 0.634 mol/kg.
To find the number of moles in 1.0 kg of NaCl, we first need to convert the mass from kilograms to grams (1.0 kg = 1000 g). Then, we need to divide the mass by the molar mass of NaCl to find the number of moles. The molar mass of NaCl is approximately 58.44 g/mol, so 1000 g / 58.44 g/mol = 17.1 moles of NaCl.
12,4439 kg of gold contain 63,177 moles.
When 1.35 kg of butane is burned, approximately 49,290 kJ of heat energy is released.

Answer: 15 kg = 2.4 stone.
This depends on the specific element or compound.
5.00 kg of Cu is equivalent to 78,68 moles.
The molality of a solution is calculated by dividing the moles of solute by the mass of the solvent in kilograms. In this case, the molality would be 2 moles / 6 kg = 0.33 mol/kg.
