Answer:
0.768 kg
Explanation:
Step 1: Given data
- Mass of ammonium nitrate (solute): 27.8 g
- Molality of the solution (m): 0.452 m
Step 2: Calculate the moles corresponding to 27.8 g of ammonium nitrate
The molar mass of ammonium nitrate is 80.04 g/mol.
Step 3: Calculate the mass of water
The molality is equal to the moles of solute divided by the kilograms of solvent (water).
Answer:
<em>An electrical circuit is an unbroken path along which an electrical current occurs and/or will pass. The basic electrical circuit consists of a power supply, two conductive wires (one end of each being connected to each cell terminal) and a small light to which the free ends of the wires leading out of the cell are attached. If the links are made right, the circuit will "close"</em>
Answer:
Plants release more carbon dioxide into atmosphere than expected. ... Plants use photosynthesis to capture carbon dioxide and then release half of it into the atmosphere through respiration. Plants also release oxygen into the atmosphere through photosynthesishesis to capture carbon dioxide and then release half of it into the atmosphere through respiration. Plants also release oxygen into the atmosphere through photosynthesis.
