BeauTo calculate the molarity of a solution, you first need to find the number of moles of the solute. In this case, the molar mass of CuSO4 · 5H2O is 249.68 g/mol. So, 75 g is equal to 0.3 moles (75g / 249.68 g/mol). Next, divide the moles of the solute by the volume of the solution in liters to get the molarity. In this case, the molarity is 0.3 moles / 1.0 L = 0.3 M.

What is the molality of a solution by dissolving 2 moles of NaOH in 10kg of water?
10kg of water contains 10l of water. So morality is 0.2mildm-3.
How many cups are in 40 mL?
There are approximately 0.169 cups in 40 mL.
What is the final volume if 10L of methane reacts with 20L of Oxygen at 100c and two atmospheres?
The reaction between methane and oxygen to form carbon dioxide and water is balanced as follows: CH4 + 2O2 -> CO2 + 2H2O. Using the ideal gas law, we can calculate the final volume by determining the number of moles of methane and oxygen reacting and then finding the volume of the products formed at the same conditions of temperature and pressure.
How many moles of gas are present in a 10L container when 3.84atm of pressure is exerted at 35 Celsius?
Using the ideal gas law (PV = nRT), we can calculate the number of moles of gas present in the container. First, convert the temperature to Kelvin (35°C + 273 = 308K). Then plug in the values: 3.84 atm * 10 L = n * 0.0821 Latm/molK * 308 K to solve for n. This gives approximately 1.5 moles of gas in the container.
What fraction of 10 liters is 5240 ml?
5240 ml is equivalent to 5.24 liters. To find the fraction, divide 5.24 liters by the total amount of 10 liters. Therefore, the fraction of 10 liters that 5240 ml represents is 5.24/10 or 0.524.
