What is the Atomic weight of iodine-126?
126 atomic mass units. 53 protons 73 neutrons
What is the weight of oxalic acid?
Formula of oxalic acid is H2C2O4.2H2O. Therefore, the equivalent weight of the acid is molecular weight divided by n-factor = 126/2 = 63.
How much is 126 kg in pounds?
The answer is 57.153 kg (approx.). Kilogram is the SI unit of mass and pound is an imperial unit of mass. To convert from pound to kg, multiply the pound unit by 0.453592.
How do you tell the number of moles in a compound if given the number of grams?
Multiply the mass of the compound by the conversion factor based on the percent composition of the element in the compound
How many does 126 kg equals in pounds?
2.77 lbs. The actual conversion of 1 kilogram is equal to 2.204622622 pounds. For everyday use, rounding to 2.2 should be enough. One pound is 0.45359237 kilogram, or 0.45 kg for everyday use.

What is the mass of 2 moles of water (H2O)?
A mole of HNO3 weighs 63g (1 + 14 +16x3). Therefore, two moles weigh, 2 x 63 =126 g
What is the molarity of a solution of 12.9 grams of fructose in 31.0 grams of water?
First, convert the mass of fructose to moles using its molar mass. Then, calculate the moles of water using its molar mass. Finally, divide the moles of fructose by the volume of the solution (in liters) to determine the molarity.
How many moles are contained in 15.8 grams of C6H12O6?
To find the number of moles in 15.8 grams of C6H12O6, first calculate the molar mass of C6H12O6 which is 180 g/mol (126 + 112 + 16*6). Then divide the given mass by the molar mass to get the number of moles. In this case, 15.8g / 180 g/mol = 0.088 moles.
How many moles of calcium is 126g of ca?
126 grams calcium (1 mole Ca/40.08 grams) = 3.14 moles of calcium ------------------------------
If you have the same amount of glucose and a tryglycerol (composed of lauric acid) which one will produced more energy or ATP Show your computation to justify your answer. Assume you have 3.5 moles of each?
One mole of glucose yields 36 moles of ATP through cellular respiration, while one mole of triglyceride (composed of lauric acid) yields 129 moles of ATP through beta oxidation and the citric acid cycle. Therefore, with 3.5 moles of each, the triglyceride will produce more energy by yielding 451.5 moles of ATP, compared to the 126 moles produced by the glucose.
What is the mass of 2.25 moles of iron?
The answer is 125,65 g.
What is gravity if mass is 15kg and weight is 126 newtons?
Gravity (acceleration) is equal to Force divided by mass. So, 126 / 15 = 8.4m/s^2
How many moles of HNO3 are present in 450 g of HNO3?
To determine the number of moles of HNO3 present in 450 g, we first need to calculate the molar mass of HNO3, which is approximately 63.01 g/mol. Next, we use the formula moles = mass/molar mass to find the number of moles. Therefore, 450 g of HNO3 is equal to 7.14 moles of HNO3.
Glucose C6H12O6 is a good source of food energy. When it reacts with oxygen carbon dioxide and water are formed. How many liters of CO2 are produced when 126 g of glucose completely react with oxygen?
The balanced chemical equation for the reaction is: C6H12O6 + 6O2 -> 6CO2 + 6H2O The molar mass of glucose is 180 g/mol, so 126 g of glucose is 0.7 moles. From the equation, 1 mole of glucose produces 6 moles of CO2, so 0.7 moles of glucose will produce 4.2 moles of CO2. Using the ideal gas law, at STP conditions, 4.2 moles of CO2 will occupy 94.5 liters.
What mass of KClO3 must be decomposed to produce 126 L of oxygen gas at 133 degrees C and 0.880 ATM?
