Best ResponseYou've already chosen the best response.0That will give you weight in kg. If you need it in something else, you need to convert kg to that something else

Best ResponseYou've already chosen the best response.0@Larryboxaplenty so I'll be dividing 7.53×10^10 by 5,000,000,000?

Best ResponseYou've already chosen the best response.0dw:1442782613471:dw You multiply the mass of one particle by 5 billion. The one is there so show that the unit "particles" cancel

Best ResponseYou've already chosen the best response.01 mill = 10^6 10 mill = 10^7 100 mill = 10^8 1 bill = 10^9 10 bill = 10^10 5^10 = 9.765 million. 5.0 x 10^9 is scientific notation. my 5x10^9 should have been 5.0 x 10^9

Best ResponseYou've already chosen the best response.0multiply (7.53*10^10) by (5.0 x 10^9) = (7.53*5) * 10^(10+9) = 37.65 * 10^1 = 3.765
