Question

Calculate the mass, in kg, of each sample.

Part A. 3.44x10^26 cadmium atoms

Part B. 6.14x10^27 nickel atoms

Part C. 9.03x10^27 manganese atoms

Part D. 1.54x10^29 lithium atoms

Answer 1

Answer #1

part A

step 1 convert atoms to mole = 3.44 *10²⁶ / 6.022 * 10²³ mol ^-1 = 571.238 moles

step 2 calculate mass from moles = 571.28 mol *Molar mass of Cd = 571.28 mol* 112.411 g/mol =64231gm= 64.231 Kg

repeat above steps for parts b, c d in similar fashion
