501 g = ng, (Use the 8 step conversion method. Express your answer using scientific notation. Include a space before and after the "x", and use the "^" for the exponent) *

Answer : 501 g = 5.01 × 10¹¹ ng

Explanation :

The conversions used to convert gram to nano-gram is:

1 g = 10 dg

1 dg = 10 cg

1 cg = 10 mg

1 mg = 1000 μg

1 μg = 1000 ng

As we are given:

Convert 501 g to ng.

As,

1 g = 10 dg

So,

501 g = 501 × 10 dg

         = 501 × 10 × 10 cg                                   ( 1 dg = 10 cg )

         = 501 × 10 × 10 × 10 mg                          ( 1 cg = 10 mg )

         = 501 × 10 × 10 × 10 × 1000 μg                 ( 1 mg = 1000 μg )

         = 501 × 10 × 10 × 10 × 1000 × 1000 ng       ( 1 μg = 1000 ng )

501 g = 501000000000 ng = 5.01 × 10¹¹ ng

Therefore, 501 g = 5.01 × 10¹¹ ng

the answer is 0.42 is that is an option. this question provides no info
