1 mole of any substance is approximately 6.022*10^23 atoms (Avogadro's number)
So
(4.90*10^31 atoms) * (1 mole / 6.022*10^23 atoms) = 8.14*10^7 moles

Estimate of 4567-1346=3221
Answer:
angle 2 is 43 as the opposite side of the angle is always equal angle 1 and 3 are:
step 1
43+43=86
step 2
360-86=274
step 3
274÷4=68.5
we subtracted 86 with 360 because 360 is the sum of all the angles we then divided the answer by 2 as we were suppose to find two angles angle 1 and 3 are opposite angles so they both will be same
hope this information helps u :)
