Answer:
0.86
Step-by-step explanation:
Its just multiplication
(A) 4.03 x 10^14
403,000,000,000,000
Scientific notation is of the form
a * 10 ^b
where a is a number from 1 to a number less than 10
Put the decimal in the number
403,000,000,000,000.
We need to move the decimal 14 places to the left to get the number to be between 1 and 10
4.03000000000000 so the b is 14
Since we moved it to the left b is positive
We can drop the extra zeros at the end (after the last nonzero digit)
4.03 *10^14
Density in decimal can be written as 0.0001429 gram per liter
We have given density of oxygen is
We have to convert this density in decimal form
We know that can be written as
So
So density in decimal can be written as 0.0001429 gram per liter
