How many atoms of carbon are in 4.00*10^-8 grams of C3H8?
A. 1.64*10^15
B. 2.34*10^11
C. 1.89*10^14
D. 4.66*10^2
E. 4.00*10^4
This is how i solved it. Can someone please tell me if its right?
4*10^-8 g of C3H8 * 1mol of C3H8/44g of C3H8 * 3mol of C/1mol of C3H8 * 6*10^23 atoms of C/1 mol of C =1.7*10^15
