WebThe coefficient of static friction between the block and the wall is 0.250. (a) Determine the possible values for the magnitude of P that allow the block to remain stationary. (b) Describe what happens if ∣ P∣ has a larger value and what happens if it is smaller. WebApr 6, 2024 · Dissolve 9.31 g of #Na_2S_2O_3 * 5H_2O# into 250mL water.. Molarity is moles/Liter. 0.150 M in 250mL is ¼ of 0.150 moles/L, or 0.0375 moles/0.25L. #Na_2S_2O_3 * 5H_2O# just has the extra mass (moles) of water to consider. That is irrelevant to this problem because we are already given the molar mass for the compound.
How much 0.05 M HCl solution can be made by diluting 250 mL …
WebMar 1, 2024 · Answer: Volume = 19.68 ml Explanation: The equation of the reaction is given as; HNO3 + KOH ---> KNO3 + H2O 1 mol of HNO3 reacts 1 mol of KOH Converting 0.276 g of KOH to mol; Number of moles = Mass / Molar mass Number of moles = 0.276g / 56.1056 g/mol Number of moles = 0.00492 Since the mole relationship is 1 = 1; WebCharacteristics: Available with either 5/64” Standard or 7/64” corona resistant wall silicone rubber insulation Silicone formulations suitable for UV, Ozone moisture exposure.

WebJul 9, 2024 · Biology High School answered Calculate the average maximum height for all three trials when the mass of the bottle is 0.125 kg, 0.250 kg, 0.375 kg, and 0.500 kg. Record your calculations in Table A of your Student Guide. When the mass of the bottle is 0.125 kg, the average maximum height of the beanbag is (____) m. WebNov 21, 2024 · The mass of the bob is 0.250 kg. The length of the string is 22.0 cm. The angle made by the string to the vertical is 24 degrees. The centripetal force in the vertical direction can be given as, The centripetal force in the horizontal direction can be given as, As the force in horizontal direction is equal to the force in vertical direction. Thus, WebDec 21, 2024 · Explanation: The concentration can be expressed as molarity as follows: Molarity = NaCl moles / liters of solution We are already given the number of moles (0.150 mol) so we need to calculate the liters of solution. We convert mL to L: 250.0 mL * = 0.250 L Now we can calculate the molarity of the NaCl solution: incompetent word origin
