What volume of 0.131 M BaCl2 is required to react completely with 42.0 ml of .453 MNa2SO4. This is the net ionic equation for the reaction. Ba2 plus plus SO42---- BaSO4. Correct answer equals 145 ML?
first of all, you need to recognize that one mole of Na2SO4 is reacting with one mole of BaCL2. so find the moles of the NaSO4, then you automatically have the moles of the BaCL2. if you get the moles of the BaCL2, its easy to calculate the volume of it because you already have the MOLARITY. good luck
How many calories are required to increase the temperature of a 27.3 g sample of copper from 36.2 degrees Celsius to 74.4 degrees Celsius?
I will work in Joules, then convert to calories.q(Joules) = mass * specific heat * change in temperature Cq = (27.3 g Cu)(0.385 J/gC)(74.4o C - 36.2o C)= 402 Joules (1 calorie/4.184 Joules)= 96.1 calories===========

What mass of glucose must be metabolized in order to prodce 145g of water?
To determine the mass of glucose that must be metabolized to produce 145 grams of water, we can use the balanced equation for the combustion of glucose: (C_6H_{12}O_6 + 6O_2 \rightarrow 6CO_2 + 6H_2O). From the equation, 1 mole of glucose produces 6 moles of water. The molar mass of water (H₂O) is approximately 18 g/mol, so 145 g of water is about 8.06 moles (145 g / 18 g/mol). Therefore, to produce this amount of water, approximately 1.34 moles of glucose are needed (8.06 moles of water / 6). The molar mass of glucose (C₆H₁₂O₆) is about 180 g/mol, so the mass of glucose required is approximately 241.2 grams (1.34 moles × 180 g/mol).
How do you calculate mass loss percentage?
1. Original Mass minus Current Mass = Mass loss2. Now divide your answer by your Original Mass, and then multiply by 100(%)Example: 145 lbs - 130 lbs = 15 lbs,divide (15/145) = 0.103and then multiply 100% x 0.103 = 10.3%

The average mass of 3 men is 77kg The average mass of 2 of the men is 72.5kg What is the mass of the 3rd man?
The everage mass of three men is: (a + b) / 3 = 77, where a is mass of two first men combined and b is a mass of third man. The everage mass of two men is: a / 2 = 72.5, therefore a = 145, and (145 + b) / 3 = 77 145 + b = 231 b = 231 - 145 = 86 Answer: Mass of the third man is 86 kg.
