in a particular company the amount of money to the nearest Naira and spent by workers on transportation to work day they were recorded as follows: 30 50 60 120 200 80 90 74 240 236 125 40 75 110 120 220 130 180 60 90 112 150 210 245 135 140 80 100 125 215 240 50 60 180 190 180 148 120 88 138 195 248 130 140 150 154 208 225 65 145 a) construct a grouped frequency distribution of this data taking equal intervals: 0-49, 50-99, ​

number of molecules / avogadro's number * molecule molecular = mass

explanation:

we define a gram-molecular weight as the mass of one mole of any element or compound. a mole contains avogadro's number of units (molecules) –  

6.022

. so, dividing the number of molecules by avogadro's number gives us the number of moles. multiplying that by the molecular weight gives us the mass. from the periodic table we find the gram-molecular weight of u to be238 and of f to be19. so,  

u

will have a gram-molecular weight of 352g.
