How many moles of oxygen atoms are in 6.6E-1 moles of CO? Only give the numeric value of your answer. D

We have 6.6 *10^-1 or 0.66 moles O

Explanation:

Step 1: Data given

Number of moles CO = 6.6 * 10^-1 = 0.66 moles

Step 2: Calculate moles O

For 1 mol CO we gave 1 mol O

For 0.66 moles CO we have 0.66 moles O

0.66 moles O = 6.6 *10^-1 moles O

We have 6.6 *10^-1 or 0.66 moles O

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

x

10

23

. 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

f

6

will have a gram-molecular weight of 352g.
