we the puzzle and get the me and get the message, use your calculator to do the calculations. Then invert the ulator and read off the message word(s). For example, "11345" is "shell". Insert the message ords in the sentences at the bottom of the page. Round all atomie masses to one decimal before using them to calculate the following. It a zero is in the decimal of the answer you can ignore the decimal. 1 a) i) Calculate the mass of 100 moles of Arsenic 7492 1) What is the mass of 10 moles of sodium? m) Add the answer in (ii) to the answer in (i) 1 Add the atomic mass of nitrogen to the answer in (iii) Word answer to (a) What is the mass of 250 moles of Calcium? b) i) 11) How much does 3279 moles of Carbon weigh? m) Add the molar mass of H, to the sum of the answers in i and ii iv) Add the answer in la(iv) to the answer in (iii) above Word answer to (b) c) i) What is the mass of 10 moles of Germanium? 11) Subtract the atomic mass of atomic oxygen from the above answer = Word answer to (C) d) i) Multiply the answer in Ic (ii) above by 10 ii) Add the mass of 10 moles of Neon to (i) iii) Subtract 197 from (ii) Word answer to (d) It is said that in the water , and hot rises from the 2) Mass of 7.0873 x 10" molecules of Oxygen (round To a whole number Word answer 2) I hope this did not your mind.

Answer 1

1) 100 moles of arsenic will have mass = 100 x 75 =7500 gm

2) 10 moles of sodium = 10 x 23 = 230gm

3) add 7500 and 230 ---> 7500+ 230 = 7730 gm

4) atomic mass of nitrogen = 14gm

14 + 7730 = 7744
