NO3- So the mole ratio here is going to be 1/1. e. Srxn = 0, Hrxn = 0, The correct answer is: Srxn > 0, Hrxn < 0. The atomic mass of arsenic is 74.92 g/mol which suggests that the mass of 1 mol of arsenic atom is 74.92 g. 1 mol of arsenic atom contains 6.023 1023 number of arsenic atoms. Which of the following polymers is used in plastic food bags and wraps? 2 e. transition state. So one grants cook healthy. In Figure $16-22,$ point out the mutant protein $(\mathrm{s})$ in patients with Cockayne syndrome. Next you want to multiply by the molar mass that was given to us (74.92g/mol of Arsenic). Select one: c. 212 mL Select one: 1 Answer marfre Apr 15, 2017 #1.227 xx 10^-6# g of gold. The atomic weight can change because it depends on our understanding of how much of each isotope of an element exists. Select one: What is the average mass_ in grams, of one arsenic atom? has a total valence state of 0 (3x(+1) for the hydrogen atoms; 1x(+3) for the arsenic(III) atom; 3x(-2) for the oxygen atoms = 3+3-6 = 0). c. 82.96 mmHg What is the mass, in grams, of #3.75 xx 10^15# atoms of gold? A worker pulled a 30kg crate attached to a rope with a constant force of 25.0 N. The crate moved a distance of 6.0m. 2 moles Arsenic to grams = 149.8432 grams. d. system heats up but there is not change in the energy of surroundings. e. 16 p, 16 n, 15 e, Which of the following is a metalloid? b. What is meant by the prefix "poly"? 220 mmHg The word 'mole' has been adopted to represent the Avogadro number of atoms of an element, that is, the relative atomic mass of an element. c. 1.5 mol of a nonvolatile compound in 750 g of ethanol Select one: Multiply by the number of moles we calculated. c. 9.1 yr Well on the reaction side there are six plus six which is 12.
