Atomic weight of magnesium lab

The measured volume of hydrogen gas produced and the mass of magnesium can be used to determine the mass of magnesium required to produce one mole of hydrogen molecules from this you can deduce the relative atomic mass of magnesium. Attempting to complete chemlab: atomic weight of magnesium given: h2 (gas) (0000829g) (0000411 moles) hydrogen chloride hcl (in solution) (2157657 g) (0059177 moles) magnesium chloride mgcl2 (in solution) (0039173g) (0000411 moles) water h20 (liquid) (330000000g) (18318069) asked to calculate the following: 1. The reactivity of magnesium metal with hydrochloric acid chm 1122 – general chemistry lab ii download introduction the ideal gas law is used to define how gasses typically act there are an equal number of moles of hydrogen and magnesium used to find the molar mass of magnesium, i took the mass of the magnesium used.

Atomic weight of magnesium lab introduction the main purpose for this experimental lab is to determine the atomic weight of magnesium, as well as an underlying purpose in determining the relationship between moles evolved and consumed. Atomic weight of mg = weight of magnesium/moles of h2now on the procedure am i suppose to click 1, 2, 3 or 4, im thinking (1) and on observation what is the lab asking would it be (2) please help with this best answer 100 % (1 rating) get this answer with chegg study view this answer or. Atomic weight of mg = weight of magnesium/moles of h2now on the procedure am i suppose to click 1, 2, 3 or 4, im thinking (1) and on observation what is the lab asking would it be (2) please help with this.

Hydrochloric acid (hcl) in order to measure the atomic weight we need to measure the amount of the hydrogen gas that was evolved in reaction to the acid of the magnesium summary to measure the atomic weight of magnesium after it has been consumed, the magnesium has to be mixed with hcl. To find the molar mass of magnesium, i took the mass of the magnesium used divided by the number of moles used from trial 1, 00406 g / 0001656 moles = 2452 g/mol to find percent error, i took the absolute value of the true value minus my calculated value divided by the true value and multiplied by 100.

atomic weight of magnesium lab Magnesium chloride mgcl2 (in solution) (0039173g) (0000411 moles) water h20 (liquid) (330000000g) (18318069) asked to calculate the following: 1 calculate the atomic weight of magnesium atomic weight of mg = weight of magnesium/moles of h2 2.

Water h2o (liquid) (330000000 g) (18318069 moles)now on the observations it states: moles of hydrogen evolved, from chemical property dialog for beaker atomic weight of mg = weight of magnesium/moles of h2.

  • The atomic weight of an element is the relative weight of one of its atoms compared to c-12 with a weight of 120000000:::, hydrogen with a weight of 1008, to oxygen with a weight of 1600.
  • 1 atomic weight of magnesium lab introduction the purpose of this lab is to determine the atomic weight of magnesium after it is consumed by hydrochloric acid (hcl) in order to measure the atomic weight we need to measure the amount of the hydrogen gas that was evolved in reaction to the acid of the magnesium.

By measuring the amount of gas produced, the molecular weight of magnesium was calculated using chemlab, 30 ml 2m hcl was added to 300 ml h2o 10 mg magnesium was then added to the solution after measuring the amount of hydrogen produced, the molecular weight (grams per mole) of magnesium was calculated. The calculation of the molecular weight using the weight of magnesium and the amount of hydrogen gas released was facilitated by the used of the balanced equation describing the reaction between magnesium and hcl.
